Task: Answer the multiple choice question.
Query: Which drug has a 1.386\% 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, or d without using any additional words.
Options:
a) CCN(CC)S(=O)(=O)c1ccc(C(=O)Oc2cc(C)[nH]c(=O)c2[N+](=O)[O-])cc1
b) Cc1ccc(NC(=O)N2CCN(Cc3ccc4c(c3)OCO4)CC2)cc1
c) COc1ccc(NC(=O)CN(C)CC(=O)Nc2ccccc2SC)cc1
d) CCOC(=O)c1sc(NC(=S)NC(=O)C2CC2)cc1C
Answer: a. CCN(CC)S(=O)(=O)c1ccc(C(=O)Oc2cc(C)[nH]c(=O)c2[N+](=O)[O-])cc1
