Task: Answer the multiple-choice question.
Query: Which drug exhibits a -40.540% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a O=C(c1cc(COc2cccc(C(F)(F)F)c2)on1)N1CCSCC1
b CCCCCN(C(=O)COC(=O)CSc1ccc([N+](=O)[O-])cc1)c1c(N)n(CCCC)c(=O)[nH]c1=O
c O=C(CN1CCN(S(=O)(=O)c2ccccc2)CC1)N1CCc2ccccc21
Answer: b. CCCCCN(C(=O)COC(=O)CSc1ccc([N+](=O)[O-])cc1)c1c(N)n(CCCC)c(=O)[nH]c1=O
