The **general solution** of a differential equation contains:
- No arbitrary constants
- As many arbitrary constants as the order of the equation
- Exactly one arbitrary constant always
- More constants than the order of the equation
Show answer and solution
Correct answer: B. As many arbitrary constants as the order of the equation
An $n$-th order DE has a general solution with $n$ arbitrary constants.
Particular solutions arise when constants are fixed by initial/boundary conditions.
