Task: Answer the multiple choice question.
Query: Which drug has a 5.904\% 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] CCc1nnc(NS(=O)(=O)c2ccc(NC(=S)NC(=O)c3ccc(OC)cc3)cc2)s1
[b] Cc1[nH]c(=O)c(C#N)c(C)c1CSc1ncccn1
[c] O=C(CC1S/C(=N/N=C/c2c[nH]c3ccccc23)NC1=O)Nc1ccccc1
[d] Cc1cccc(-c2noc(CCC(=O)NCc3ccco3)n2)c1
Answer: b. Cc1[nH]c(=O)c(C#N)c(C)c1CSc1ncccn1
