Task: Answer the multiple choice question.
Question: Which compound has a 1.495\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(CCCCl)NC1=NN(c2ccccc2)C(=O)C1
(b) N#Cc1cc(-c2ccccc2)cnc1Sc1ccc(Cl)cc1
(c) C[C@H]1CCC/C=C/[C@@H]2C[C@H](O)C[C@H]2[C@H](O)/C=C/C(=O)O1
Answer: a. O=C(CCCCl)NC1=NN(c2ccccc2)C(=O)C1
