Problem statement: Answer the multiple choice question.
Query: Which drug has a 16.886\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a. O=c1[nH]c(S)c(/C=C2\C=Nc3ccccc32)s1
b. Cc1c(C(=O)N2CCN(c3ccc(F)cc3)CC2)sc2ncnc(N3CCN(c4ccccn4)CC3)c12
c. CCOC(=O)CSc1nnc(NC(=O)CCc2ccccc2)s1
Answer: a. O=c1[nH]c(S)c(/C=C2\C=Nc3ccccc32)s1
