Task: Answer the multiple choice question.
Question: Which compound exhibits a -40.643% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: O=c1[nH]ncn2cccc12
b: O=C(c1ccc(Br)s1)N1CCN(C/C=C/c2ccccc2)CC1
c: CC1CCCCN1S(=O)(=O)c1coc(C(N)=O)c1
Answer: b. O=C(c1ccc(Br)s1)N1CCN(C/C=C/c2ccccc2)CC1
