Task: Answer the multiple choice question.
Query: Which compound has a 15.926\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a: O=C(C[n+]1ccccc1)c1ccc(-c2ccccc2)cc1.[Br-]
b: COc1ccccc1CNC(=O)CN1C(=O)c2ccccc2S1(=O)=O
c: N#Cc1ccccc1COC(=O)CCC(=O)c1cccs1
d: CCn1c2ccccc2c2cc([N+](=O)[O-])ccc21
Answer: b. COc1ccccc1CNC(=O)CN1C(=O)c2ccccc2S1(=O)=O
