Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a -24.699\% 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 other words.
Options:
a: CCOC(=O)C1CCN(S(=O)(=O)c2ccc(Cl)cc2OC)CC1
b: O=C(COC(=O)c1ccc(N2CCCC2=O)cc1)c1ccc(OC(F)F)cc1
c: O=C(Nc1cccc(Cl)c1)C1CCCCC1
d: CCn1nc(C(=O)Nc2nc3ccccc3[nH]2)c2ccccc2c1=O
e: O=C(/C=C/c1cccs1)Nc1ccncc1
Answer: a. CCOC(=O)C1CCN(S(=O)(=O)c2ccc(Cl)cc2OC)CC1
