Task: Answer the multiple choice question.
Query: Which drug exhibits a -4.904\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: O=C(CCn1c(=O)c2ccccc2n(Cc2cccc([N+](=O)[O-])c2)c1=O)N1CCc2ccccc2C1
b: Cc1ccc(N(C)C(=O)C2CCCN2S(=O)(=O)c2ccc3c(c2)n(C)c(=O)c(=O)n3C)cc1
c: CCCNC(=O)c1ccc2c(c1)S(=O)(=O)c1ccccc1C2=O
d: CCCN1CCN(CCCNC(=O)CN2C(=O)c3cccnc3Oc3ccc(C)cc32)CC1
Answer: a. O=C(CCn1c(=O)c2ccccc2n(Cc2cccc([N+](=O)[O-])c2)c1=O)N1CCc2ccccc2C1
