When a muon and an antimuon annihilate, the event would produce a minimum of 2 photons of the same energy.
So we can find the energy of 1 photon from the rest mass energy of a muon which allows you to find the wavelength.

You can apply the various conservation laws for particle physics to eliminate the options:
conservation of baryon number
conservation of lepton number
conservation of charges
And use the following “conservation law” for weak interaction to determine the possible products.
Strangeness can change by 0 or ±1 for weak interactions.
