Task: Answer the multiple choice question.
Question: Which drug exhibits a 9.138\% 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, b, c, or d without using any additional words.
Options:

b CCN1C(=O)C(=C2C=C(C)OC(C)=C2)C(=O)N(CC)C1=S
c CC(=O)N1CCN(C(=O)CSc2cc(C)c(Br)cc2C)CC1
d CC(C)c1nnc(NC(=O)CCS(=O)(=O)Cc2ccccc2)s1
Answer: b. CCN1C(=O)C(=C2C=C(C)OC(C)=C2)C(=O)N(CC)C1=S
