Task: Answer the multiple choice question.
Query: Which drug has a 12.722\% 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) COc1ccc2c(c1)c1nnc(SCC(=O)N3C(C)CCCC3C)nc1n2C
(b) O=C(COC(=O)c1ccccc1Br)NCCC1=CCCCC1
Answer: b. O=C(COC(=O)c1ccccc1Br)NCCC1=CCCCC1
