Task: Answer the multiple-choice question.
Query: Which drug has a 12.798\% 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] Cc1ccc(NC(=O)CSc2nnc(NC(=O)CN3CCOCC3)s2)cc1
[b] Cc1ccc(S(=O)(=O)/N=C(\CCl)N2CCOCC2)cc1
[c] CCOC(=O)Cn1c(-c2ccccc2)ccc(C#N)c1=O
[d] COc1ccc(Cc2nc(-c3ccc(Cl)cc3)no2)cc1
[e] O=C(Nc1ccncc1)c1sc2ccccc2c1Cl
Answer: c. CCOC(=O)Cn1c(-c2ccccc2)ccc(C#N)c1=O
