Task: Answer the multiple-choice question.
Question: Which drug exhibits a 15.306\% 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) COc1ccc(-n2c(SCC(=O)Nc3ccc(NC(C)=O)cc3)nc3ccccc3c2=O)cc1
(b) C=CCN1C(=O)CC(C(=O)NC)SC1=Nc1ccc(C(=O)OCC)cc1
(c) Cc1cccc(NC(=O)CCn2c(=O)oc3ccccc32)c1
Answer: b. C=CCN1C(=O)CC(C(=O)NC)SC1=Nc1ccc(C(=O)OCC)cc1
