Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.466\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: CCOc1ccc2nc(NC(=S)NCc3ccccc3)sc2c1
b: CCOC(=O)COc1cc(C)nc2nc(-c3ccccc3)cn12
c: COc1cccc(-c2nnc3n2N=C(c2cc(OC)ccc2OC)CS3)c1
d: Cc1ccc(C)c(SCC(=O)OCC(=O)NCc2ccccc2)c1
e: O=C(NNc1nc2cc3c(cc2s1)OCCO3)c1ccccc1
Answer: a. CCOc1ccc2nc(NC(=S)NCc3ccccc3)sc2c1
