Task: Answer the multiple-choice question.
Query: Which drug has a 14.933% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] O=c1c(C(c2ccc(Br)cc2)c2c(O)nc3n(c2=O)CCS3)c(O)nc2n1CCS2
[b] CC#CC(=O)N1CCC(C(=O)Nc2ccc(Oc3ccccc3)nc2)CC1
Answer: a. O=c1c(C(c2ccc(Br)cc2)c2c(O)nc3n(c2=O)CCS3)c(O)nc2n1CCS2
