How did Cooper know the quantum data is what Murph needed to solve the gravity equation?
In Interstellar Professor Brand reveals only to Murph (on his deathbed) that Plan A, solving the equation was 'impossible'. I am struggling to reconcile;
A) How Murph knows that it is quantum data needed to solve the equation.
B) How Cooper knows that in order to save humanity, he must send the quantum data to Murph i.e. that the solution to the equation requires quantum data.
I get that with A) Murph could join the dots and realise what to do with this data but it is B) I am more struggling with. Was this just a last Hail Mary or had he figured out himself the quantum data would solve the equation, did he have a scientific background?
In no way is this a criticism of the movie, I would just like to understand it more.

I have found the answer after rewatching a selection of scenes and am posting it for the benefit of others.
Dr. Mann tells Cooper that Professor Brand solved the equation years ago but it didn't reconcile quantum mechanics and relativity. He goes on to say you need more data... you need to see into a black hole.

How does Cooper send the quantum data to Murph?
Cooper has TARS transmit the quantum data to his helmet as binary code. As he does this, he finds the moment in time when Murph left her window open during the dust storm and uses his hand to manipulate gravity and give his former self the coordinates to NASA in the dust lines on the floor.How did Murph know the ghost was her dad?
In the end humanity was saved because of the powerful love between a father and a daughter. That same love is why Murph was able to figure out her ghost was her father. "love transcends time and space".How did Murph know brand was alive?
She knew, because she knew Brand was on the mission, and in amongst the data transmitted there was some how information pertaining to the ship, or coordinates, etc, that lead her to the conclusion that Brand was with or near when he went into the black hole, and she used intellect and intuition and guess that she made ...Interstellar - Quantifiable Connection Scene 1080p HD
