Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.668\% 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 additional words.
Options:
a: COc1ccc(/C=N/NC(=O)C(C)n2cnc3ccccc3c2=O)cc1
b: O=C(Nc1cccc(C(F)(F)F)c1)Nn1cnnc1
c: O=C(COC(=O)C1(c2ccc(Cl)cc2)CCCC1)NCc1ccco1
d: COc1cccc(CN2C(=O)N(C(C)C)C(N(O)C(=O)NC(C)C)C2(C)C)c1OC
e: COC(=O)C(C)N(C#N)c1nc(NC(C)C)nc(SC)n1
Answer: c. O=C(COC(=O)C1(c2ccc(Cl)cc2)CCCC1)NCc1ccco1
