Task: Answer the multiple choice question.
Query: Which drug has a 15.195\% 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] Cc1cccc2cc(C(c3nnnn3Cc3ccc4c(c3)OCO4)N3CCC(C)CC3)c(=O)[nH]c12
[b] CC(=O)Oc1ccc(C2OC(=O)c3ccccc3N2C(C)=O)cc1
[c] Cc1csc(C(=O)NN)c1N(C)C
[d] COc1cccc(C(=O)N(Cc2nc(-c3cccc(C)c3)no2)C(C)C)c1OC
Answer: c. Cc1csc(C(=O)NN)c1N(C)C
