Task: Answer the multiple choice question.
Query: Which drug exhibits a -38.749\% 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)c1c(N)n(Cc2ccco2)c2nc3ccccc3nc12
b.) O=C(CSc1n[nH]c(-c2ccccc2O)n1)NC1CCCCC1
c.) CCc1nc(C(N)=O)c2[nH]c(=O)n(-c3ccc(OC)cc3OC)c2n1
Answer: a. CCOC(=O)c1c(N)n(Cc2ccco2)c2nc3ccccc3nc12
