DATA across 3 columns and output to 4th

Dear all,

I have a certain Excel workbook which has data stored in 3 columns. Column A has around 300 entries, column B has around 980 and similar for column C. There are certain similar entries between columns A and B.

What I wish to do is to find all the similar entries between A & B, then match it to the corresponding entry in column C and then give a output in the same worksheet

I'm attaching the sample for easier understanding and analysis

Any guidance would be appreciated, solving this basically finishes my entire project
