Problem statement: Answer the multiple choice question.
Query: Which drug has a 10.646\% 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 other words.
Options:
a: COc1cc2ccccc2cc1C(=O)O
b: C#CCOc1ccc(Br)cc1/C=N/O
c: CC(C)(O)C#Cc1ccccc1C(=O)NC(CC(N)=O)C(=O)O
d: NC(=O)COC(=O)c1sc2cc(F)ccc2c1Cl
Answer: a. COc1cc2ccccc2cc1C(=O)O
