Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.401\% 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 additional words.
Options:
(a) O=C(Cc1ccc(NC2=NC3CS(=O)(=O)CC3S2)cc1)Nc1ccc(F)cc1
(b) Cc1cccc(NC(=O)CSCC(=O)N=c2sccn2C)c1
(c) CCOC(=O)c1c(NC(=O)CSc2c[nH]c3ccccc23)sc2c1CCCC2
(d) CCOC(=O)c1ccc(N2C(=O)C=CC2=O)cc1
Answer: a. O=C(Cc1ccc(NC2=NC3CS(=O)(=O)CC3S2)cc1)Nc1ccc(F)cc1
