Problem statement: Answer the MCQ question.
Query: Which drug exhibits a 19.207\% 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: CCCc1cc(=O)oc2cc(OCC(=O)NC3CCN(Cc4ccccc4)CC3)ccc12
b: CCOC(=O)C(CC(=O)O)=C(c1ccccc1)c1ccccc1
c: N#Cc1cnn2c(N)c(-c3ccc(Cl)cc3)cnc12
Answer: b. CCOC(=O)C(CC(=O)O)=C(c1ccccc1)c1ccccc1
