Task: Answer the multiple-choice question.
Query: Which drug has a 9.727\% 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=c1[nH]ncn1-c1ccc(Br)cc1
(b) CC1Sc2ccc(S(=O)(=O)CCC(=O)Nc3cc(F)ccc3F)cc2NC1=O
(c) CCOC(=O)C(=O)/C(C#N)=C/Nc1ccc(Cl)cc1
(d) CSc1ccccc1NC(=O)CN(C)C(=O)/C=C/c1ccccc1
Answer: a. O=c1[nH]ncn1-c1ccc(Br)cc1
