Which one of the following satisfies the relationship D d a: a D D:: R r b: ?
- AD D A
- BR R R
- Cb R RCorrect
- DB B r
Explanation
To solve this analogy, observe the pattern in the first pair D d a to a D D.
First, the third letter of the group moves to the first position. In the first pair, small a moves to the front. In the second pair, small b must move to the front.
Second, the first letter of the group is repeated twice in its capital form to fill the remaining positions. In the first pair, capital D becomes D D. In the second pair, capital R becomes R R.
Applying this logic to R r b, the small b moves to the front, followed by two capital Rs. This results in b R R. Therefore, option C is correct.
