Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 20.060\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a Cc1ccc(C)c(OCCSc2nnc(C)c(=O)[nH]2)c1
b Cc1ccc(C)c(N2CCN(c3ncccc3[N+](=O)[O-])CC2)c1
c O=C(NCCCc1nc2ccccc2[nH]1)c1ccco1
d Cn1c(=O)n(C)c2cc(S(=O)(=O)Nc3ccc(F)cc3)ccc21
Answer: c. O=C(NCCCc1nc2ccccc2[nH]1)c1ccco1
