Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 2.105% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a COc1ccc(CCNC(=S)Nc2ccccc2C)cc1
b O=C(c1nc2ccc(Cl)cn2c1CNCCc1cnccn1)N1CCCCCCC1
Answer: a. COc1ccc(CCNC(=S)Nc2ccccc2C)cc1
