Task: Answer the multiple-choice question.
Question: Which drug exhibits a 6.473\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a Cn1nc(C(=O)NCCN2CCOCC2)c2ccccc2c1=O
b COc1ccc(-c2nc(CN3CCN(C(=O)c4ccco4)CC3)c(C)o2)cc1OC
c COC(=O)CSc1nc(C)cc(C(F)(F)F)c1C#N
d Cn1c(=O)[nH]c2sc3c(c2c1=O)CC(C)(C)OC3
Answer: c. COC(=O)CSc1nc(C)cc(C(F)(F)F)c1C#N
