Task: Answer the multiple choice question.
Question: Which drug exhibits a 3.572\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a) CNC(=O)N(O)C1N(C)C(=O)N(Cc2ccccc2)C1(C)C
b) Cc1cc2oc(=O)cc(CN(C)Cc3ccccc3F)c2cc1Cl
c) O=C(Nc1ccc2c(c1)OCO2)C1CCN(C(=O)c2ccc(Br)cc2)CC1
Answer: a. CNC(=O)N(O)C1N(C)C(=O)N(Cc2ccccc2)C1(C)C
