Task: Answer the multiple choice question.
Query: Which compound has a -41.752\% 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 or b without using any additional words.
Options:
a: CCC1C=C(c2ccccc2)C=CN=C1N(CC)CC
b: COc1ccc(NC(=O)c2ccc3c(c2)C(=O)N(Cc2cccnc2)C3=O)cc1
Answer: a. CCC1C=C(c2ccccc2)C=CN=C1N(CC)CC
