Option 2
Step-by-step explanation:
In ΔABC,
AD is a median and point M is the point of concurrence of all medians.
Therefore, point M is a centroid of the triangle.
And M will divide line AD in the ratio of 1 : 2 (Ratio of AM : MD)
Since, length of MD = 2 cm
Therefore, length of AM = 4 cm
Total length of AD = AM + MD
= 2 + 4
= 6
Option 2 will be the answer.
