The last sentence means that even if we remove the heat and pressure, the carbon remains in its new form once it has been changed into diamond.

Ok, now the options..

It is clear that " remaining this way " doesn't go with a singular subject.. graphite.

So.. we use the word remains. Now, we are left with option D or option E.

The main difference in these two options are the words - " although " & " when "

We use X although Y , if we are sure that Y is given. And we use " when " if we want to imply the if/then statement. See the below examples..

"You can take the bus to the city, although you cannot drive", then it's a fact that you cannot drive.

"You can take the bus to the city when you cannot drive", then this is basically implies "if/then" statement: if you can't drive, then you can take the bus.

So.. based upon this we choose option E as it correctly uses the word " when ".
