Task: Answer the multiple choice question.
Query: Which drug exhibits a 4.563\% 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. COc1cccc(CNc2ccc(F)c([N+](=O)[O-])c2)c1O
b. C/C(=N\NC(=S)NCCc1ccccc1)c1cccc(Br)c1
c. COc1cccc(C2=CC(c3ccc(N(C)C)cc3)n3ncnc3N2)c1
d. CCn1c(NC(=O)c2ccccc2F)c(-c2cccs2)c(=O)c2ccccc21
Answer: d. CCn1c(NC(=O)c2ccccc2F)c(-c2cccs2)c(=O)c2ccccc21
