Problem statement: Answer the multiple choice question.
Question: Which drug has a 7.284% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) Cc1[nH][nH]c(=O)c1[C@@H](c1ccccc1[N+](=O)[O-])C(C#N)C#N
(b) S=C(Nc1cccc(Cl)c1)Nc1ccc2cn[nH]c2c1
(c) CCCCCn1c(=O)[nH]c2cc(C(=O)NCCN3CCC(C)CC3)ccc2c1=O
(d) Cc1ccc(N2C(=O)CC2(C#N)c2ccc(OCc3ccccc3)cc2)cc1
Answer: a. Cc1[nH][nH]c(=O)c1[C@@H](c1ccccc1[N+](=O)[O-])C(C#N)C#N
