Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a -54.343\% 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 Cn1c(=O)c(C(=O)Nc2ncccc2O)c(O)c2ccccc21
b Cc1ccc(C)c(CSc2ccc3nnc(-c4ccccn4)n3n2)c1
c COc1ccc(C2C(C(=O)c3cccs3)=C(O)C(=O)N2c2nncs2)cc1
d CCOc1cc(NC(=O)C2CC2)c(OCC)cc1NC(=O)c1ccccn1
e O=C(O)C(Cc1ccccc1)N1C(=O)/C(=C/c2cccc3ccccc23)SC1=S
Answer: b. Cc1ccc(C)c(CSc2ccc3nnc(-c4ccccn4)n3n2)c1
