Task: Answer the multiple choice question.
Question: Which compound exhibits a 15.074\% 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, c, or d without using any additional words.
Options:
a N[C@@H](Cc1ccc(O)c(I)c1)C(=O)O
b COc1ccc(-c2nc(C#N)c(NCC3CCCO3)o2)cc1OC
c COc1ccccc1OCC(O)COC(N)=O
d COc1ccccc1OCCC(=O)OCC(=O)NC(=O)NC(C)(C)C
Answer: a. N[C@@H](Cc1ccc(O)c(I)c1)C(=O)O
