To solve the problem of matching the acronyms with their correct meanings, we need to understand each term listed in Set-I and how it corresponds to the explanations in Set-II. This is a basic knowledge-based question often seen in exams to assess familiarity with common ICT terminology.

1. DPI (Dots Per Inch): This measures the resolution of various devices such as printers and monitors. It quantifies how many individual dots can be placed in a line within the span of one inch. Therefore,
   (a) DPI corresponds to (i) "Measures resolution of a laser printer."
2. CRT (Cathode Ray Tube): This is a technology used in traditional computer monitors and televisions. A CRT consists of one or more electron guns, and a phosphorescent screen is used in older models of screens. So, (b) CRT matches with (iii) "A type of computer monitor."
3. NIC (Network Interface Card): This is a hardware component that allows a computer to connect to a network. It implements the hardware level of the OSI model. Hence, (c) NIC suits with (iv) "Enables a computer to connect to other computers."
4. CD-ROM (Compact Disc Read-Only Memory): This is a type of optical disc capable of storing data and is read but not written to by a computer. Therefore, (d) CD-ROM fits with (ii) "An example of read-only storage."

By analyzing each acronym and its corresponding meaning, we conclude that the correct matches are:

• (a)-(i)
• (b)-(iii)
• (c)-(iv)
• (d)-(ii)

Therefore, the correct option is (a)-(i), (b)-(iii), (c)-(iv), (d)-(ii).
