Best answer
The correct choice is (a) One

Best explanation: Let’s understand this by an example:

Suppose we want to find the solution for 9x-3 = 0

9x-3 = 0

9x = 3

Therefore x = 1/3

We can see that this linear equation has only one solution. i.e. x = 1/3

It means that there is only one number which satisfies the given equation.
