Question

The order of the differential equation of a family of curves represented by an equation containing four arbitrary constants, will be

• A. $2$
• B. $4$
• C. $6$
• D. None of these

Answer 1

The correct option is B

$4$

Explanation for the correct option

Given, differential equation of family of curves with $4$ arbitrary constants.

So the order of the differential equation is $4$

Hence, the correct option is $\left(\mathrm{B}\right)$
