i Definitely know that There is no such thing as a mixed order DE.
but i am asking in out of three options, which is the correct option for my question.

There's basically just 2 concepts being asked. First, the order of a differential equation. And second whether a differential equation is linear or non-linear. Do you know what these concepts are, and how they are defined?

It's a little bit hard to read your image but I think that first derivative is third order. So what are your ideas on this? Do you know what the order of a differential equation is? Do you know how to determine whether a differential equation is linear or not?

(It is possible for a partial differential equation to be of "mixed order" but not an ordinary differential equation.)
