Task: Answer the multiple-choice question.
Query: Which drug has a -23.494% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) CCCCn1c(O)c(C(C)=NCc2cccnc2)c(=O)[nH]c1=O
(b) O=C(CNCCC1=CCCCC1)Nc1ccccc1N1CCCCCC1.O=C(O)C(=O)O
Answer: a. CCCCn1c(O)c(C(C)=NCc2cccnc2)c(=O)[nH]c1=O
