Problem statement: Answer the multiple-choice question.
Query: Which drug has a -50.839\% hERG inhibition at a concentration of 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(Nc1nnc(-c2ccco2)o1)c1ccc(N2C(=O)CCC2=O)cc1
[b] CCCCOC(=O)Nc1cccc(C(C)=O)c1
[c] O=C1CC(N2CCN(C/C=C/c3ccccc3)CC2)C(=O)N1Cc1cccs1
[d] O=C(c1cccc(S(=O)(=O)NCc2ccccc2)c1)N1CCCC1
Answer: c. O=C1CC(N2CCN(C/C=C/c3ccccc3)CC2)C(=O)N1Cc1cccs1
