Task: Answer the multiple choice question.
Query: Which drug has a 4.949% 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: CSc1ccc(CCNC(=O)CN2C(=O)c3cccnc3Oc3ccc(C)cc32)cc1
b: COc1cc(CCc2ccc3c(c2)OCO3)oc(=O)c1
c: Cc1[nH][nH]c(=O)c1C(c1ccc([N+](=O)[O-])cc1)c1c(C)[nH][nH]c1=O
d: O=C1/C(=C/c2cccc([N+](=O)[O-])c2)CCc2ccccc21
e: Cc1nnc2ccc(-c3ccc(NS(=O)(=O)c4ccc(Cl)s4)cc3)nn12
Answer: b. COc1cc(CCc2ccc3c(c2)OCO3)oc(=O)c1
