Problem statement: Answer the multiple choice question.
Query: Which drug has a 4.974% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O/N=C\c1cccn1-c1ccc(Br)cc1
(b) CCOC(=O)/C(C#N)=C1\C=CN(C)C(C)=N1
(c) O=C(CSc1nncn1-c1ccccc1)c1c[nH]c2ccccc12
Answer: b. CCOC(=O)/C(C#N)=C1\C=CN(C)C(C)=N1
