Which of the following steps is INCORRECT while constructing \[\Delta LMA,\]right angled at M, given that \[LN=5\text{ }cm\]and\[MN=3\text{ }cm\]?

Step 1. Draw MN of length 3 cm.

Step 2. At M, draw MX1MN. (L should be somewhere on this perpendicular).

Step 3. With N as centre, draw an arc of radius 5 cm. (L must be on this arc, since it is at a distance of 5 cm from N).

Step 4. L has to be on the perpendicular line MX as well as on the arc drawn with centre N. Therefore, L is the meeting point of these two and ALMA/ is obtained.

A)  Only Step 4

B)  Both Step 2 and Step 3

C)  Only Step 2

D)  None of these
