Task: Answer the MCQ question.
Query: Which compound exhibits a 12.529\% 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(NCc1n[nH]c(=S)n1-c1ccc(Br)cc1)c1ccc(S(=O)(=O)N2CCCCC2)cc1
b: Cc1nn(Cc2ccccc2)c2c1C(c1ccccc1)C(C#N)=C(N)O2
c: CC1(C)CC(=O)C(N=Nc2cc(S(=O)(=O)N3CCOCC3)ccc2Cl)=C(O)C1
d: Cc1ccc(/C=N/N(Cc2ccccc2)c2ccccc2)o1
e: O=C(CSC(=S)N1CCCC1)N1CCN(S(=O)(=O)c2cccc(F)c2)CC1
Answer: b. Cc1nn(Cc2ccccc2)c2c1C(c1ccccc1)C(C#N)=C(N)O2
