Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 8.129\% 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 additional words.
Options:
a: Cc1ccccc1NC(=O)NC(N)=O
b: Cc1ccc2c(Cl)cc(Cl)c(OCC(=O)N(C(C)C)C(C)C)c2n1
c: CCN(C(=O)c1cccc(NC(=O)c2ccccc2)c1)C1CCCCC1
d: COc1cc2nc(NC(=O)c3ccc(Cl)cc3)[nH]c(=O)c2cc1OC
Answer: a. Cc1ccccc1NC(=O)NC(N)=O
