Task: Answer the multiple choice question.
Question: Which drug exhibits a 7.890\% 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 additional words.
Options:
a. COc1ccc(Br)cc1-c1nc(C)c(C(C)=O)n1O
b. CCCCSc1nnc(-c2ccccc2N)c(=O)[nH]1
c. COCCN(C(=O)CSc1nc2ccccc2c(=O)n1CC(C)C)c1c(N)n(Cc2ccccc2)c(=O)[nH]c1=O
Answer: b. CCCCSc1nnc(-c2ccccc2N)c(=O)[nH]1
