Task: Answer the multiple choice question.
Question: Which compound exhibits a -8.172\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
a O=C(NCc1ccccc1Cl)c1ccc[nH]1
b COc1ccc(/C(N)=N/OC(=O)Cc2ccccc2OC)cc1
c CCCc1cc(C(=O)Nc2ccc(F)cc2F)no1
d CC(=O)NC(=S)NNC(=O)CCc1ccccc1
e O=C(NCc1ccco1)c1cc(-c2ccccc2)on1
Answer: a. O=C(NCc1ccccc1Cl)c1ccc[nH]1
