Copy form Cell(s) on Sheet A to Sheet B if Cell A changes, then clear cells on Sheet A

Ok, this may have been asked before but here is what I am working with.

I am new to coding in Excel with MB and/or Macros so any assistance is appreciated. I have looked over some other code already posted as answers to similar questions but am unsure how I would modify it for my needs. 

Excel workbook with 2 Sheets. 
Sheet 1 has data in 13 rows with Columns A through F containing data for each Row
Data Starts at Cell A4 With Cell C4 being a drop-down with 2 options 
Calls A4 and B4 are static info
Cell F4 automatically changes based on the option in the drop-down
Cells D4 and E4 are manual entry data

What I am looking to do for the 13 rows of data is the following 
When Cell C4 is changed from Option 1 to Option 2 copy Cells A4, D4, E4, and F4 to Sheet 2 starting in Row 2 then clear the contents of Dells D4 and E4 on Sheet 1
The next time this is triggered it should populate the next row in sheet 2

This will need to work for all 13 rows in sheet 1

Sample data on Sheet 1 

Sample data for Sheet 2 after the copy
Cells A4 to A2, D4 to B2, E4 to C2, F4 to D2 Cell E2 is auto-populated when the copy is done.
