Problem statement: Answer the MCQ question.
Question: Which drug exhibits a 14.617\% human ether-à-go-go related gene (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 other words.
Options:
a: O=C1C2=C(CCCC2)C(=O)N1c1cccc(OCCBr)c1
b: COc1ccc(Cl)cc1S(=O)(=O)N(C)CC(=O)NCc1ccccn1
c: O=C(Nc1nc2ccc(S(=O)(=O)N3CCCC3)cc2s1)C1CCCCC1
d: CC1CCCN(c2cc3c(cc2[N+](=O)[O-])C(=O)N(c2ccccc2)C3=O)C1
e: COc1cccc2c1OCC(C(=O)O)C2
Answer: a. O=C1C2=C(CCCC2)C(=O)N1c1cccc(OCCBr)c1
