I think sir was wrong at the end, F max can be easily found by only analyzing system c as well.All you have to do is writing 2nd law for block 2 and plugging the a value that you get from block 2 into the system c.Because a-c must be equal to a-2, if sliding doesn't occur

Sir so is it the minimum force required to keep the blocks together?

[solsticetwo]

In the 2nd approach, when F is low, the a is negative. How can?
