Task: Answer the multiple choice question.
Query: Which drug exhibits a 9.340\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) COc1ccc(S(=O)(=O)N(Cc2ccccc2)c2ccccc2C(=O)N2CCOCC2)cc1
(b) CC1(C)c2[nH]c3ccccc3c2C[C@@H]2C(=O)N(Cc3ccc(F)cc3)C(=O)N21
(c) CN1N=C(C(C)(C)C)CC1=O
(d) Nc1nnc(SCC(=O)NC2CCCC2)s1
(e) Cc1cc(Nc2ccccc2F)nc(-c2ccccc2O)n1
Answer: c. CN1N=C(C(C)(C)C)CC1=O
