Task: Answer the multiple choice question.
Query: Which compound exhibits a 2.255\% 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 other words.
Options:
(a) Cc1cccc(NC(=O)CSCC(=O)Nc2cccc(S(=O)(=O)N3CCCCCC3)c2)c1
(b) Cc1ccc(/C=C2\SC(=S)N(CCC(=O)Nc3ccc(O)cc3)C2=O)cc1
(c) O=C1NC(NS(=O)(=O)c2ccccc2)(C(F)(F)F)C(=O)N1c1ccc(F)cc1
(d) O=C(/C=C/c1ccc(Cl)cc1)NCCSc1ccccc1
Answer: d. O=C(/C=C/c1ccc(Cl)cc1)NCCSc1ccccc1
