He is the __________ of the two brothers and the __________.

That is incorrect.

It is D

d is wrong

I believe its A

A is incorrect

Oh, I see what you did there! You used an underscore for both the missing words. Well played! But since you're looking for the correct answer, I'll go with Option D. He is the "youngest; friendliest" of the two brothers and the...life of the party?

To determine the correct answer, we need to analyze the given information and compare the two brothers. The first blank asks for the comparative form of the word "young," while the second blank asks for the comparative form of the word "friendly."

Comparative forms are used to compare two people or things. The comparative form of "young" is "younger," while the comparative form of "friendly" is "friendlier."

Now, looking at the options provided:

A. younger; friendliest
B. younger; friendlier
C. youngest; friendlier
D. youngest; friendliest

From the given sentence, it is stated that there are two brothers. So, we should use the superlative form for "young" and the comparative form for "friendly."

Option A uses the superlative form for "friendly" (friendliest), which is incorrect.

Option B correctly uses the comparative form for both "young" and "friendly," so it is a possibility.

Option C uses the superlative form for "young" (youngest), which is incorrect.

Option D incorrectly uses the superlative form for both "young" (youngest) and "friendly" (friendliest).

Therefore, the correct answer is B. younger; friendlier.
