Task: Answer the multiple choice question.
Question: Which drug has a 12.386\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] CCOc1ccc(NC(=O)c2cc(C)nc3ccccc23)cc1
[b] Cc1ccccc1NS(=O)(=O)c1cc(OCC(N)=O)c(C)cc1Cl
[c] CCn1c(=O)c2cc(C(=O)Nc3ccc(OC)cc3OC)sc2c2ccccc21
[d] O=[N+]([O-])c1cc(C=Nc2cccc3c(O)cccc23)ccc1Cl
[e] C=CCn1c(C(CCCC)CC(O)COCCC)n[nH]c1=S
Answer: c. CCn1c(=O)c2cc(C(=O)Nc3ccc(OC)cc3OC)sc2c2ccccc21
