Task: Answer the multiple choice question.
Query: Which drug exhibits a 6.198\% 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, or c without using any other words.
Options:
a: CC(=O)c1cccc(CN2CCCC(C(=O)Nc3cccc(-n4cccn4)c3)C2)c1
b: Cc1nnc(SCC(=O)NC(C)(C)C)n1C1CCCCC1
c: CC(C)CCN1CCN(Cc2nc(-c3ccccc3)cs2)CC1CCO
Answer: b. Cc1nnc(SCC(=O)NC(C)(C)C)n1C1CCCCC1
