Task: Answer the multiple-choice question.
Question: Which drug exhibits a 4.444\% 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, or c without using any additional words.
Options:
(a) COc1ccc(C(C)NC(=O)c2ccccc2Cl)cc1OC
(b) Cc1c(NC(=O)CN2C(=O)NC3(CCCC3)C2=O)c(=O)n(-c2ccccc2)n1C
(c) CCN1C=C(C(=O)OC)C(c2cccc(C)c2)C(C(=O)OC)=C1
Answer: a. COc1ccc(C(C)NC(=O)c2ccccc2Cl)cc1OC
