Task: Answer the multiple choice question.
Query: Which drug exhibits a 5.651\% 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 CCOC(=O)N1CCN(C(=O)c2noc3c2COc2ccccc2-3)CC1
b COc1ccc(NC(=S)Nc2ccc(S(N)(=O)=O)cc2)c(C)c1
c Cc1nnc(-c2ccccc2)o1
Answer: a. CCOC(=O)N1CCN(C(=O)c2noc3c2COc2ccccc2-3)CC1
