Problem statement: Answer the multiple choice question.
Question: Which drug has a -0.653\% 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) COc1ccc(/C=C/C(=O)O)cc1COc1ccccc1C
b) COc1ccc(C2CC(=O)N3C(=C2C#N)SCC3(O)c2ccccc2)cc1
c) Cc1cccc(Nc2nnc(SCC(=O)Nc3ccc(C(=O)O)cc3)s2)c1
d) COc1cccc(C2C(C#N)=C(N)OC3=C2C(=O)CCC3)c1OC(=O)c1ccco1
Answer: a. COc1ccc(/C=C/C(=O)O)cc1COc1ccccc1C
