Task: Answer the multiple choice question.
Question: Which compound exhibits a 5.536\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: Cc1nn(Cc2c(Cl)cccc2Cl)c(C)c1NC(=O)c1cn(-c2ccccc2)nc1-c1ccccc1
b: O=C(Nc1ccccc1)Nc1ccncc1
c: O=C(Cc1c[nH]c2ccccc12)NCc1cccs1
d: Cc1nnc(SCC(=O)Nc2sc3c(c2C(=O)c2ccccc2)CCCC3)s1
e: CCOC(=O)C(NC(C)=O)(Nc1cccc(F)c1)C(F)(F)F
Answer: b. O=C(Nc1ccccc1)Nc1ccncc1
