he was a german mathematician.

he developed hilbert's axioms.

he wrote a biography on euclidhilbert's improvements to geometry are still used in textbooks today.

The option which is not correct about David Hilbert is that He wrote a biography on Euclid.
He was a mathematician, not a biographer - although he did mention Euclid in his research, it was not to talk about his life, but to point out the inaccuracies in his theories. 
If you need to choose more than one answer, perhaps choose that He invented the point - he just named the point, he did not invent it.
However, if you need only one answer, then choose just the fourth option.
