Problem statement: Answer the multiple-choice question.
Question: Which drug has a -2.095\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: O=C(CCSc1nnc(-c2ccncc2)o1)Nc1ccc(Cl)cc1
b: CCCC(=O)Nc1sc(C(=O)Nc2cccc(N)c2)c(C)c1C(=O)OC
c: OCC1CCN(Cc2cn(Cc3ccccc3)nc2-c2cc3ccccc3o2)CC1
Answer: a. O=C(CCSc1nnc(-c2ccncc2)o1)Nc1ccc(Cl)cc1
