the degree and order respectively of the differential

The degree and order respectively of the differential equation $$\frac{{dy}}{{dx}} = \frac{1}{{x + y + 1}}$$ are :

A. $$1,\,1$$

B. $$1,\,2$$

C. $$2,\,1$$

D. $$2,\,2$$

Answer : $$1,\,1$$

Solution :
Since order of the highest derivative in the given differential equation is $$1$$ and exponent of the derivative is also $$1$$ therefore degree and order is $$\left( {1,\,1} \right).$$
