Task: Answer the multiple choice question.
Question: Which compound exhibits a 14.499\% 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 COC(=O)c1cccc(NC(=O)CSCc2ccccc2)c1
b CCOc1ccccc1C(=O)NCC(=O)NCCc1ccc(S(N)(=O)=O)cc1
c Sc1oc(-c2ccccc2)cc1C=Nc1ccccc1
d COc1ccc(-c2ccc(=O)n(Cc3ccccc3)n2)cc1
Answer: d. COc1ccc(-c2ccc(=O)n(Cc3ccccc3)n2)cc1
