Task: Answer the multiple choice question.
Question: Which drug exhibits a -6.941\% 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: CC(C)CC(NC=O)C(=O)O.COc1cc2c(cc1OC)C13CCN4CC5=CCOC6CC(=O)N2C1C6C5CC43
b: COc1ccc(C2CC3(CC(C)(C)NC(=O)N3)Oc3cc(O)ccc32)cc1
Answer: b. COc1ccc(C2CC3(CC(C)(C)NC(=O)N3)Oc3cc(O)ccc32)cc1
