Answer: Option (D) is the correct answer.

Step-by-step explanation:

Shape of DNA molecule is like a twisted ladder. This structure of DNA is solved by James Watson and Francis Crick.

According to Watson and Crick base pairing:

  • A (Adenine) pairs with T (Thymine) with the help of two hydrogen bonds.
  • G (Guanine) pairs with C (Cytosine) with the help of three hydrogen bonds.

Thus, given strand of DNA is CGTAT and its complementary strand will be GCATA.
