Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.357% 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, or c without using any additional words.
Options:
a.) CCC1(Cc2ccccc2)NC(=O)c2ccccc2O1
b.) C=CCN1C=C2C(=O)C(C)(OC(=O)c3cnc4ccccc4n3)C(=O)C=C2C=C1/C=C/COC
c.) COc1ccccc1OCCn1c(=O)n(C)c2ccccc21
Answer: a. CCC1(Cc2ccccc2)NC(=O)c2ccccc2O1
