Problem statement: Answer the multiple-choice question.
Question: Which drug has a 1.776\% 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: O=C(COc1ccc(Br)cc1)Nc1ccccc1C(=O)N1CCOCC1
b: CCN(CC)CCn1c2c(c(SCC(=O)Nc3nc(C)cs3)nc1=O)CCC2
Answer: a. O=C(COc1ccc(Br)cc1)Nc1ccccc1C(=O)N1CCOCC1
