Answer:

(B). TACCCGATCAGAA .

Explanation:

DNA is made up of nitrogen bases, pentose sugar, and phosphate molecules. The nitrogen bases include adenine (A), thymine (T), cytosine (C), and guanine (G).

According to complementary base-pairing rule, adenine makes bonds with thymine and cytosine makes bond with guanine in a double-stranded DNA molecule. So, the complementary strand for 'ATGGGCTAGTCTT' will be 'TACCCGATCAGAA.'

Thus, the correct answer is option (B).
