A single-stranded DNA molecule contains 40 nucleotides with equal amounts of A, C, G, and T. This DNA strand can combine with a complementary DNA strand to form a double-stranded DNA molecule. Which of the following double-stranded DNA molecules would denature at a lower temperature than the 40 base-pair double-stranded molecule described above?

a 30 base-pair molecule in which 40% of the bases are guanines
a 20 base-pair molecule in which 10% of the bases are thymines
a 10 base-pair molecule in which 20 % of the bases are cytosines
