Task: Answer the MCQ question.
Query: Which drug exhibits a -2.406\% 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 other words.
Options:
a O=C(NNC(=O)c1nn(-c2ccc(F)cc2)ccc1=O)c1ccc(Cl)cc1
b O=C(OCn1nnc2ccccc2c1=O)c1cccc(S(=O)(=O)N2CCOCC2)c1
Answer: a. O=C(NNC(=O)c1nn(-c2ccc(F)cc2)ccc1=O)c1ccc(Cl)cc1
