Task: Answer the multiple-choice question.
Query: Which drug has a 20.438\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a Cc1nn(-c2ccccc2)c2c1C(c1cccnc1)N1C=C(S(=O)(=O)N3CCCCC3)C=CC1=N2
b COc1ccccc1N(C)S(=O)(=O)c1ccc(C(=O)Nc2nccs2)cc1
c CN=C1SC(CC(=O)Nc2sc3c(c2C#N)CCCC3)C(=O)N1C
d Cc1ccc(NC(=O)NN2CCOCC2)cc1
e Cc1c(C)c(C)c(S(=O)(=O)NCCc2ccccn2)c(C)c1C
Answer: c. CN=C1SC(CC(=O)Nc2sc3c(c2C#N)CCCC3)C(=O)N1C
