Task: Answer the multiple choice question.
Question: Which drug exhibits a 9.148\% 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 additional words.
Options:
a: O=C(c1cc(F)ccc1F)C1CCCN(C(=O)CCc2cnccn2)C1
b: CCCOC(=O)c1ccc(NC(=O)C2C3C=CC(O3)C2C(=O)O)cc1
c: Cn1c(C(=O)O)ccc1S(=O)(=O)N(Cc1ccccc1)Cc1ccccc1
d: CC(NC(=O)c1ccccc1)c1nnc(SCc2nc3ccccc3c(=O)[nH]2)n1C
e: Cc1ccc2nc(NC(=O)CSc3nnc(C)c(=O)n3N)sc2c1
Answer: a. O=C(c1cc(F)ccc1F)C1CCCN(C(=O)CCc2cnccn2)C1
