Task: Answer the multiple-choice question.
Query: Which drug exhibits a 2.049\% 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 additional words.
Options:
a CC1CN(C(=O)c2cccc(Oc3ccccc3)c2)CC(C)O1
b COc1ccccc1NC(=S)N(Cc1ccc(Cl)cc1)CC1CCC(C(=O)O)CC1
c COc1cc2[nH]c(=S)n(Cc3ccc(C)o3)c(=O)c2cc1OC
Answer: c. COc1cc2[nH]c(=S)n(Cc3ccc(C)o3)c(=O)c2cc1OC
