B Correct answer
Explanation

The speaker's age = brother's age + 12 (brother is 12 years younger). Sister's age = speaker's age - 6 (sister is 6 years younger). Given brother is 11: speaker = 11+12=23, sister = 23-6=17. Option B (17) is correct. Option A (18) would require brother to be 12, not 11.
