Problem statement: Answer the MCQ question.
Question: Which drug exhibits a 9.965\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a O=C(O)CC(Cc1ccc(Br)cc1)C(=O)O
b Cc1ccc(Cn2c(SCC(C)C)nc3c2c(=O)[nH]c(=O)n3C)cc1
c CCN(CC)c1ccc(/C=C(\C#N)C(=O)NCc2ccco2)cc1
d Cc1nc2ccccc2c(=O)n1NCc1cccs1
Answer: a. O=C(O)CC(Cc1ccc(Br)cc1)C(=O)O
