Task: Answer the multiple-choice question.
Query: Which drug exhibits a 27.957\% 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, c, or d without using any other words.
Options:
(a) O=C(NCC1CCCCC1)c1ccc(=O)[nH]c1
(b) Cc1ccccc1C(=O)NNS(=O)(=O)c1cccc([N+](=O)[O-])c1
(c) Cc1ccc(OCC(=O)Nc2cccc(-c3nnc(-c4ccccc4)o3)c2)c(C)c1
(d) CCOc1cc(S(=O)(=O)NCc2cccnc2)c(C)cc1C
Answer: a. O=C(NCC1CCCCC1)c1ccc(=O)[nH]c1
