Task: Answer the MCQ question.
Query: Which compound exhibits a 9.552\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: Cn1cccc1/C=N/NC(N)=S
b: C=CCNc1nc(N)c([N+](=O)[O-])c(NCc2ccccc2)n1
c: O=C(O)c1cc(S(=O)(=O)NC(Cc2c[nH]c3ccccc23)C(=O)O)ccc1Cl
d: COc1ccccc1CCNC(=O)CCn1nc(C)c2c(C)n(-c3ccccc3)nc2c1=O
Answer: b. C=CCNc1nc(N)c([N+](=O)[O-])c(NCc2ccccc2)n1
