Task: Answer the multiple choice question.
Query: Which drug exhibits a 21.917% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(/C=C/Nc1ccccc1Oc1ccccc1)c1ccco1
(b) CSCc1ccc(C(=O)N2CCC(N3CCC(C(=O)NC(C)C)CC3)CC2)o1
(c) CN(C)/C=C1/C(=O)N(c2ccc([N+](=O)[O-])cc2)N=C1c1ccccc1
Answer: a. O=C(/C=C/Nc1ccccc1Oc1ccccc1)c1ccco1
