Show answer & explanation
Correct answer: C
To determine the total number of A's siblings, we must evaluate the sufficiency of the provided statements:
Step-by-Step Analysis
Statement I: "A has two brothers and one sister."
This statement explicitly lists the number of siblings A has: 2 brothers + 1 sister = 3 siblings. This information is sufficient to answer the question.
Statement II: "A is the youngest child in the family."
This statement describes A's position in the birth order but provides no information about the total count of A's siblings. There could be one sibling or ten; we cannot know. This information is insufficient on its own.
