Matriculation is 10th so yes they are asking for 10th certificate. I guess the reason for the same is that these are historical records and are much harder to falsify given the time period. You can provide 12th as well since you said your mom's name is not there. For my friend, they asked 10th and 12th both.
In my friend's case the letter was clear to provide the old passport for the sponsor. My advice is to provide yours and your mothers. Let them deal with it and see which they want in the absence of the direction in the letter.
If I read email carefully below (highlighted) ,it has my UCI number and name. This makes me believe that they are requesting sponsor's 10th cert and old Indian passport. It serves two purpose, to check my mother's name on passport and my country of origin
