Problem statement: Answer the multiple choice question.
Query: Which drug has a 1.877\% 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: O=C(CSc1nncn1-c1cccnc1)Nc1ccccc1C(F)(F)F
b: O=C(NCCCN1CCOCC1)c1ccccc1NS(=O)(=O)c1ccc(Br)cc1
Answer: a. O=C(CSc1nncn1-c1cccnc1)Nc1ccccc1C(F)(F)F
