Select the word-pair that best represents a similar relationship to the one expressed in the pair of words given below.(The words must be considered as meaningful English words and must not be related to each other based on the number of letters/number of consonants/vowels in the word.)
CD : Computer

Correct option is B

Let's analyze the relationship between the given pair:

• CD : Computer — A CD is an object used with or associated with a computer. The relationship is one of an essential component or accessory that is used with the primary item.

Now, let's look at the options:

• (a) Pen : Paper — A pen is used to write on paper. While related, the relationship is not similar to CD and Computer, where one is a component associated with the other.

• (b) Engine : Scooter — An engine is a critical component of a scooter. This relationship is similar to CD and Computer because the engine is an essential part of the scooter.

• (c) Card : Greeting — A card is used to deliver a greeting, but the relationship isn't as directly comparable to CD and Computer.

• (d) Pin : Safety — A safety pin is a specific item with a designated purpose, but it doesn't reflect the relationship like CD and Computer.

The word-pair Engine : Scooter best represents a similar relationship to CD : Computer because an engine is an integral component of a scooter, just as a CD is associated with a computer.

Therefore, the correct answer is (b) Engine : Scooter.
