Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 13.155\% 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(S(=O)(=O)NCC(c2cccnc2)N2CCN(C)CC2)cc1OC
b: O=C(Cn1ccc2ccccc2c1=O)NCCC(=O)Nc1ccc2c(c1)OCCO2
c: O=C(O)c1[nH]c2ccc(F)cc2c1NC(=O)C1CC1(c1ccccc1)c1ccccc1
d: CCN(Cc1nc2cc(OC)c(OC)cc2c(=O)[nH]1)C(=O)c1ccc(S(=O)(=O)N(C)C)cc1
Answer: a. COc1ccc(S(=O)(=O)NCC(c2cccnc2)N2CCN(C)CC2)cc1OC
