Task: Answer the multiple choice question.
Question: Which drug exhibits a 12.909\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a O=C(CN1C(=O)CSc2ccccc21)N/N=C/c1ccco1
b COc1ccc(NC(C)=O)cc1NC(C)c1nc2sc(C)c(C)c2c(=O)[nH]1
c COc1cccc(-n2c(SCC(=O)N3CCCCC3)nc3c([nH]c4ccccc43)c2=O)c1
d COc1ccc(-c2cc(=O)oc3cc(OC(C)C(=O)NC(Cc4c[nH]c5ccc(O)cc45)C(=O)O)ccc23)cc1
Answer: c. COc1cccc(-n2c(SCC(=O)N3CCCCC3)nc3c([nH]c4ccccc43)c2=O)c1
