Task: Answer the multiple choice question.
Question: Which compound exhibits a 15.638\% 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, b, or c without using any additional words.
Options:
a: O=C(CCc1ccccc1)n1nc(-c2ccccc2)nc1NCc1ccco1
b: COc1ccc(-c2nsc(SCC(=O)NCC3CCCO3)n2)cc1
c: N#Cc1c(NC(NC(=O)c2ccco2)C(=O)c2ccccc2)sc2c1CCCC2
Answer: a. O=C(CCc1ccccc1)n1nc(-c2ccccc2)nc1NCc1ccco1
