Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 16.779\% 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(NC(=S)Nc1ccccc1N1CCCC1)c1ccccc1Br
b O=C(NCCN1CCCCC1)c1ccc2c(c1)OCCO2
c Cl.NC(=O)c1c(NC(=O)c2c(F)cccc2F)sc2c1CCN(Cc1ccccc1)C2
Answer: a. O=C(NC(=S)Nc1ccccc1N1CCCC1)c1ccccc1Br
