Task: Answer the multiple choice question.
Query: Which drug exhibits a 9.934\% 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 CC1(C(=O)NCCOc2ccccc2Cl)CC1(Cl)Cl
b COCCNC(=O)c1ccc(-n2c(SCc3cc(F)ccc3F)nc3ccccc3c2=O)cc1
c O=C(NC(=S)N1CCCC1)c1ccc(Cl)cc1
d CCCN(CC(=O)Nc1ccccc1C)C(=O)Cc1coc2cc(C)ccc12
Answer: a. CC1(C(=O)NCCOc2ccccc2Cl)CC1(Cl)Cl
