Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -21.587% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) COc1ccccc1N(Cc1ccccc1)S(=O)(=O)c1cccc(C(=O)O)c1
b) O=C(NCc1nnc(SCC(=O)N2CCCc3ccccc32)o1)c1c(F)cccc1Cl
c) CCOC(=O)CC(=O)CSc1nc2ccc(C)cc2cc1C#N
d) C=CCNC(=O)NC(=O)COC(=O)COc1ccc(Br)cc1F
Answer: c. CCOC(=O)CC(=O)CSc1nc2ccc(C)cc2cc1C#N
