Task: Answer the multiple-choice question.
Query: Which compound exhibits a 7.340\% human ether-à-go-go related gene (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) COc1ccccc1C(CNc1ncccc1[N+](=O)[O-])N(C)C
b) COc1ccc(-n2nc(C(=O)NCC(=O)N3CCOCC3)c3ccccc3c2=O)cc1OC
c) COc1cc(S(=O)(=O)Nc2ncccc2C)c(OC)cc1Cl
d) CCCn1c(NCc2ccc3c(c2)OCO3)nc2ccccc21
e) O=C(c1ccc(C(F)(F)F)cc1)C1CCCN(C(=O)c2csnn2)C1
Answer: a. COc1ccccc1C(CNc1ncccc1[N+](=O)[O-])N(C)C
