Task: Answer the MCQ question.
Question: Which drug exhibits a -16.996\% 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) COC(=O)C1(C(F)(F)F)N=C(C(F)(F)F)Nc2ccc(Cl)cc21
(b) CC1=C(C(=O)NCc2ccco2)C2(CCC(C)CC2)OC1=O
(c) O=C(NCc1ccco1)c1cc([N+](=O)[O-])ccc1N1CCCCC1
(d) O=C(NNC(=O)c1cc(Cl)ccc1O)c1ccc(NS(=O)(=O)c2cccs2)cc1
Answer: c. O=C(NCc1ccco1)c1cc([N+](=O)[O-])ccc1N1CCCCC1
