Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 16.743\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) COc1cc(N2CCOCC2)ccc1C=C1C(=O)NC(=O)NC1=O
b.) CC(=O)Nc1ccc(/C=C/c2noc(-c3ccccc3O)n2)cc1
c.) O=C(Cn1cncn1)c1ccccc1Br
Answer: c. O=C(Cn1cncn1)c1ccccc1Br
