Task: Answer the multiple choice question.
Question: Which drug exhibits a 19.382\% 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) COc1ccc(S(=O)(=O)N2CCCC2)cc1C(=O)O
b) Cc1ccc(NC(=O)CN(Cc2ccccc2)S(C)(=O)=O)cc1C
c) CC(=O)COc1cc(C)cc2oc(=O)c(C)c(C)c12
d) CC(C)NC(=O)CCCn1cc([N+](=O)[O-])cn1
Answer: a. COc1ccc(S(=O)(=O)N2CCCC2)cc1C(=O)O
