Task: Answer the MCQ question.
Question: Which compound exhibits a 2.373\% 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 additional words.
Options:
[a] CCc1ccc(C2(O)CC(C(F)(F)F)=NN2C(=O)Cc2ccc([N+](=O)[O-])cc2)cc1
[b] CC(/C=N/n1c(-c2ccncc2)n[nH]c1=S)=C\c1ccco1
Answer: a. CCc1ccc(C2(O)CC(C(F)(F)F)=NN2C(=O)Cc2ccc([N+](=O)[O-])cc2)cc1
