Understanding Suffixes and Word Formation with '-ist'

The question asks us to identify which of the given words can correctly take the suffix "-ist". The suffix "-ist" is commonly used in English to form nouns that typically refer to a person who follows a particular ideology, doctrine, or principle, or practices a specific art, science, or skill.

Let's examine each word:

• (a) Hero: Adding the suffix "-ist" to "Hero" would give "heroist". While one might understand the intended meaning, "heroist" is not a standard or commonly used word in English. Related words like "heroism" (noun) or "heroic" (adjective) are standard, but "heroist" for a person who is a hero is not.
• (b) Attract: "Attract" is a verb. Adding the suffix "-ist" to "Attract" would give "attractist". This is not a standard English word. The noun related to "attract" is typically "attraction".
• (c) Flute: "Flute" is a musical instrument. Adding the suffix "-ist" to "Flute" gives "flutist". This is a standard English word meaning a person who plays the flute.
• (d) Loyal: "Loyal" is an adjective describing someone who is faithful and committed. Adding the suffix "-ist" to "Loyal" gives "loyalist". This is a standard English word referring to a person who remains loyal, often to a political cause, ruler, or government.

Based on this analysis, the words that can take the suffix "-ist" to form standard English words are "Flute" (forming "flutist") and "Loyal" (forming "loyalist"). These correspond to options (c) and (d).

Therefore, the words that take the suffix "-ist" are (c) Flute and (d) Loyal.
