Task: Answer the multiple choice question.
Question: Which compound exhibits a 9.484\% 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) CCN=c1sc(C(=O)NCCc2ccccc2)cc(=O)n1CC
(b) Cc1cc2ncn(CCCCOc3ccccc3)c2cc1C
(c) CCOc1ccc(C(=O)OCC(=O)Nc2cc(C)on2)cc1OCC
(d) O=S(=O)(Nc1ccc(Nc2ccccc2)cc1)c1ccc(F)cc1
Answer: a. CCN=c1sc(C(=O)NCCc2ccccc2)cc(=O)n1CC
