Task: Answer the MCQ question.
Question: Which drug exhibits a -1.795\% 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 COC(=O)C1=C(O)/C(=C\c2ccc(CNS(=O)(=O)c3ccccc3)o2)N=C1C
b COc1ccc(/C=C(\C#N)C(=O)C(C)(C)n2cncn2)cc1
Answer: a. COC(=O)C1=C(O)/C(=C\c2ccc(CNS(=O)(=O)c3ccccc3)o2)N=C1C
