Task: Answer the multiple-choice question.
Query: Which drug exhibits a -18.447% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a Cc1ccc(NC(=O)N(Cc2cccs2)Cc2cc3cc4c(cc3[nH]c2=O)OCO4)cc1
b O=C(CSCc1cccc(Br)c1)N1CCOCC1
c CCOC(=O)N1CC=C2C(C#N)=C(N)C(C#N)(C#N)[C@H](c3cccs3)[C@H]2C1
Answer: c. CCOC(=O)N1CC=C2C(C#N)=C(N)C(C#N)(C#N)[C@H](c3cccs3)[C@H]2C1
