Problem statement: Answer the MCQ question.
Question: Which drug exhibits a 14.456\% 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, b, c, or d without using any other words.
Options:
a COc1ccccc1NC(=O)/C=C\C(=O)O
b CCCOc1cccc(NC(=O)c2c(-c3ccccc3)noc2C)c1
c O=C1OC(c2ccc(Cl)cc2)=N/C1=C\N1CC2CC(C1)c1cccc(=O)n1C2
d CC(NC(=O)c1ccco1)c1nc(-c2ccccc2)no1
Answer: a. COc1ccccc1NC(=O)/C=C\C(=O)O
