The question asks us to find the option where the pair of words shares the same relationship as the given pair: Tissues : Histology.

First, let's understand the relationship between Tissues and Histology. Histology is the branch of biology that studies the microscopic anatomy of biological tissues. So, the relationship is 'Subject of study' : 'Branch of science that studies it'.

Analyzing the Options for the Same Relationship

We will now examine each option to see if it follows the same 'Subject of study' : 'Branch of science' relationship.

Option 1: Insects : Malacology

Malacology is the branch of zoology dedicated to the study of mollusks (like snails, slugs, clams, etc.). The study of Insects is called Entomology.

Relationship in Option 1: Insects : Malacology is incorrect as Malacology does not study Insects. This option does not share the same relationship as Tissues : Histology.

Option 2: Amphibians : Herpetology

Herpetology is the branch of zo zoology concerned with the study of reptiles and Amphibians (like frogs, salamanders, newts, etc.).

Relationship in Option 2: Amphibians : Herpetology correctly represents the relationship where Herpetology is the study of Amphibians. This matches the 'Subject of study' : 'Branch of science' relationship of Tissues : Histology.

Option 3: Shells : Ornithology

Ornithology is the branch of zoology specifically focused on the study of birds. The study of Shells (specifically mollusk shells) is called Conchology, which is a sub-field of Malacology.

Relationship in Option 3: Shells : Ornithology is incorrect as Ornithology studies birds, not shells. This option does not share the same relationship.

Option 4: Mountains : Onomatology

Onomatology is the study of proper names, especially personal names (anthroponymy) and place names (toponymy). The study of Mountains is called Orology or Orography.

Relationship in Option 4: Mountains : Onomatology is incorrect as Onomatology studies names, not mountains. This option does not share the same relationship.

Conclusion on Analogy Relationship

Comparing the relationships, only Option 2, Amphibians : Herpetology, follows the same pattern as Tissues : Histology, which is 'Subject of study' : 'Corresponding branch of science'.

Additional Information on Biological Studies

Understanding the specific fields of study within biology and other sciences is crucial for solving such analogy questions. These fields are often named using Greek or Latin roots related to the subject being studied, followed by '-logy', which means 'study of'.

• Histology: ἱστός (histós, "tissue") + -logy
• Herpetology: ἑρπετόν (herpetón, "creeping animal", referring to reptiles and amphibians) + -logy
• Entomology: ἔντομον (éntomon, "insect") + -logy
• Malacology: μαλακός (malakós, "soft", referring to mollusks) + -logy
• Ornithology: ὄρνις (órnis, "bird") + -logy
• Conchology: κόγχη (kónchē, "cockle, mussel") + -logy
