Task: Answer the multiple choice question.
Query: Which compound has a -2.132\% 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: CSc1ccc(NC(=O)N2CC=C(n3c(=O)[nH]c4ccccc43)CC2)cc1
b: CCN(CC)CCN(C(=O)c1ccc2c(c1)OCCO2)c1nc2ccc(C)cc2s1.Cl
Answer: a. CSc1ccc(NC(=O)N2CC=C(n3c(=O)[nH]c4ccccc43)CC2)cc1
