Task: Answer the multiple choice question.
Query: Which drug has a 9.729\% 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 additional words.
Options:
(a) C=CCOc1ccc(C(c2c(C(=O)O)[nH]c3ccccc23)c2c(C(=O)O)[nH]c3ccccc23)cc1
(b) O=C(CN1C(=O)c2ccccc2S1(=O)=O)N1CCN(c2ccccc2)CC1
(c) Cc1cc(=O)oc(C)c1C(=O)OCC(=O)c1ccc2ccccc2c1
Answer: b. O=C(CN1C(=O)c2ccccc2S1(=O)=O)N1CCN(c2ccccc2)CC1
