## The Attempt at a Solution

I am surely making some very silly mistake in this problem . Presuming linear momenta means magnitude of momentum , to me all four options look correct .

a) since wavelengths are same , energy is same which means momentum is same .option a) is correct .

Similarly b) , c) , d) are correct .

Or is it that the question is considering momentum as a vector (which it is ) but generally in these problems only magnitude of momentum is considered .

If this is the case , option d) is correct .

Please let me know which is correct .
