Task: Answer the multiple-choice question.
Query: Which drug exhibits a -8.875\% 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: CCCCn1c(O)c(C(C)=NC(Cc2c[nH]c3ccccc23)C(=O)OC)c(=O)[nH]c1=O
b: CN(C(=O)C1CCCC1)C1CCS(=O)(=O)C1
c: CN1CCN(C(=O)/C(=C/c2ccc(F)cc2)NC(=O)c2ccccc2)CC1
d: C=CCc1c(OC)ccc2ccc(=O)oc12
e: O=C(Nc1ccccc1)c1ccc(=O)n(Cc2cccc(Cl)c2)c1
Answer: a. CCCCn1c(O)c(C(C)=NC(Cc2c[nH]c3ccccc23)C(=O)OC)c(=O)[nH]c1=O
