Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 21.114\% 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 or b without using any other words.
Options:
a COc1ccc(/C(O)=C2/C(=O)C(=O)N(CCCN3CCOCC3)C2c2ccc(OC)cc2)cc1
b COCC1CCN(Cc2nc(-c3ccc4c(c3)OCO4)no2)C1
Answer: a. COc1ccc(/C(O)=C2/C(=O)C(=O)N(CCCN3CCOCC3)C2c2ccc(OC)cc2)cc1
