Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.534\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. COc1ccc(NC(=O)CC2C(=O)N(c3ccc(OC)cc3)C(=O)N2C(C)C)cc1
b. Cc1cc(C)c(NC(=O)CN2C(=O)NC3(CCOc4ccccc43)C2=O)c(C)c1
c. O=C(COc1cccc([N+](=O)[O-])c1)N/N=C/c1ccco1
d. Cc1cccc(C)c1NC(=O)CSc1nc(N2CCOCC2)nc(N2CCOCC2)n1
Answer: c. O=C(COc1cccc([N+](=O)[O-])c1)N/N=C/c1ccco1
