Neutrinos

11) Suppose that one of the neutrinos (in Reference below) interacts with a down quark and the outcome is one muon plus one up quark. (i) Which of the four fundamental interactions is involved in this process? List the conservation laws that apply. (ii) Identify a quantum of energy which might facilitate the interaction. (iii) Draw a Feynman diagram to represent the interaction.

Reference:
I have obtained an answer for the following question.
10)  The neutrinos that AMANDA neutrino telescope detects have passed through the earth and are rising through the ice sheet. There are an enormous number of neutrinos doing this every second. A tiny proportion of these interact with quarks within protons or neutrons in the ice to form muons. There are three generations of neutrino, state which kind of neutrino will interact in the way described, and give its symbol.

ANSWER:

There are three known types of neutrinos: electron neutrino νe, muon neutrino νμ and tau neutrino ντ, named after their partner leptons in the Standard Model.
The neutrino is an obscure particle with no electric charge and which only interacts with matter via the weak nuclear force. In recent years it has been discovered that neutrinos have a small mass, debunking the earlier assumption that it was massless. In the sun, an enormous number of neutrinos are produced in the fusion process when four hydrogen atoms transform into one helium atom.
When a neutrino interacts with matter, it can either continue as a neutrino after the interaction ("neutral current interaction") or create the corresponding charged particle ("charge current interaction"). The electron neutrino creates an electron, the muon neutrino a muon, and the tau neutrino a tau lepton.
