Task: Answer the multiple-choice question.
Question: Which drug exhibits a 7.421\% 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 other words.
Options:
a.) CC(=O)CC(C)(C)NC(C)=S
b.) CC(C)NCC1CCc2cc(CO)c([N+](=O)[O-])cc2N1
c.) O=C1CCC(=O)N(O)CCCCCNC(=O)CCC(=O)N(O)CCCCCNC(=O)CCC(=O)N(O)CCCCCN1
Answer: a. CC(=O)CC(C)(C)NC(C)=S
