Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -4.544\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: COC(=O)c1cc(NC(=O)CSc2nncn2C)cc(C(=O)OC)c1
b: Cc1cc(C)cc(NC(=O)Cc2ccc(NC3=NC4CS(=O)(=O)CC4S3)cc2)c1
c: CCNC(=O)/C(C#N)=C/c1c(N2CCN(c3ccccc3)CC2)nc2ccccn2c1=O
Answer: c. CCNC(=O)/C(C#N)=C/c1c(N2CCN(c3ccccc3)CC2)nc2ccccn2c1=O
