Task: Answer the MCQ question.
Query: Which compound exhibits a 4.765\% 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, or c without using any other words.
Options:
(a) O=C(O)[C@H]1CCCC[C@H]1C(=O)Nc1ccc(Nc2ccccc2)cc1
(b) O=[N+]([O-])c1cc(S(=O)(=O)N2CCCC2)ccc1SCCO
(c) CCN(Cc1ccccc1)S(=O)(=O)c1cc(C(=O)c2c(N)n(C)c(=O)n(C)c2=O)ccc1OC
Answer: a. O=C(O)[C@H]1CCCC[C@H]1C(=O)Nc1ccc(Nc2ccccc2)cc1
