 Hello and welcome to the session I am Deepika Pihar. Let's discuss the question which says the number of arbitrary constants in the general solution of a differential equation of fourth order are A0, B2, C3, G4. Now we know that the solution which contains arbitrary constants is called the general solution of a differential equation and the general solution of a differential equation contains as many arbitrary constants as the order of the differential equation. So let's start the solution. Now here we are asked to find the number of arbitrary constants in the general solution of a differential equation of fourth order. Now according to our key idea the number of arbitrary constants in the differential equation is equal to the order of the differential equation. Now we are given the order of the differential equation is 4 therefore the number of arbitrary constants equal to 4 and this is our option. Deep, this is the correct answer. I hope the solution is clear to you. Bye and take care.
