Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.713\% 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: COc1cccc(CN2CCNC(=O)C2CC(=O)NCCc2cccc(C)n2)c1OC
b: COc1cc2c(cc1OC)CN(C(=O)NS(=O)(=O)c1ccc(C)cc1)CC2
c: CCc1nnc(N2C(=N)SCC2=O)s1
Answer: c. CCc1nnc(N2C(=N)SCC2=O)s1
