Problem statement: Answer the MCQ question.
Question: Which drug exhibits a 7.419\% 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(COc1ccccc1)NCC(=O)NC1=NCCS1
[b] COc1ccc(-c2cc(C(=O)NCc3cccnc3)no2)cc1OC
[c] CCOC(=O)C(CC)(CC)C(=O)/C=C/c1ccc(Br)cc1
Answer: c. CCOC(=O)C(CC)(CC)C(=O)/C=C/c1ccc(Br)cc1
