The number of arbitrary constants in the general solution of a differential equationof fourth order are:(A) 0                 (B) 2                 (C) 3                 (D) 4

Explanation

To determine the number of arbitrary constants in the general solution of a fourth-order differential equation, we can follow these steps:

### Step-by-Step Solution

1. **Understanding the Order of the Differential Equation**:
A fourth-order differential equation involves the fourth derivative of a function. The general form can be expressed as:
\[
\frac{d^4y}{dx^4} = f(x, y, y', y'', y''')
