Assertion :Statement − 1 : White phosphorus is less stable where as red phosphorus is more stable. Reason: Statement − 2 : White phosphorus exist as individual P4 having more strained geometery while red phosphorus has P4 tetrahedron structure linked together.

Solution
The correct option is A Statement − 1 is true, Statement − 2 is true and Statement − 2 is correct explanation for Statement − 1.
White phosphorus has a tetrahedral basic unit where four phosphorus atoms arranged at the four corners of a tetrahedron are joined together by a total of six single bonds. This creates a very highly strained system which is unstable and very reactive.
Red phosphorus has an amormous structure (only short range order, no long range one) and is therefore a lot more stable and less reactive
