Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -55.203% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: O=C1C(=O)N(Cc2ccncc2)C(c2cccc(O)c2)/C1=C(\O)c1ccc2c(c1)OCCO2
b: O=C(NCC1CCCN1S(=O)(=O)c1cccs1)c1ccc([N+](=O)[O-])cc1
c: CCN(CC)CCCN1C(=O)C(O)=C(C(=O)c2ccco2)C1c1ccc(C)o1
d: O=C(Nc1ccc(-n2cccn2)cc1)C1CCN(Cc2ccsc2)CC1
e: Cc1n(Cc2ccccc2)c2cc([N+](=O)[O-])ccc2[n+]1Cc1ccccc1.[Cl-]
Answer: b. O=C(NCC1CCCN1S(=O)(=O)c1cccs1)c1ccc([N+](=O)[O-])cc1
