Task: Answer the multiple-choice question.
Query: Which drug exhibits a -5.639% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a: COc1ccccc1C(c1nnnn1C1CCCC1)N1CCN2CCCC2C1
b: COc1cc(/C=N/NC(=O)c2cc3ccccc3[nH]2)ccc1O
c: Cc1nc(NC(=O)c2cccc(Cl)c2)sc1C(=O)N1CCCCC1
d: O=C(CSc1nc2ccccc2c(=O)n1NC(=O)Cc1ccccc1)NCCc1ccccc1
e: COc1ccccc1NC(=O)C(C)OC(=O)C1COc2ccccc2O1
Answer: a. COc1ccccc1C(c1nnnn1C1CCCC1)N1CCN2CCCC2C1
