Task: Answer the multiple choice question.
Query: Which drug exhibits a 9.175% hERG inhibition at a concentration of 10uM?
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]c(CSc2nnnn2-c2ccccc2)nc2ccccc12
b O=C(O)CS(=O)(=O)c1ccc(C(F)(F)F)cn1
c COC(=O)c1nnn(-c2nonc2N)c1CSc1ccc(Cl)cc1
d CCOC(=O)N1CCN(C(=O)CNC(=O)c2ccc(Cl)cc2)CC1
Answer: a. O=c1[nH]c(CSc2nnnn2-c2ccccc2)nc2ccccc12
