A, B, D are correct....incorrect is C. Because forearm is the length of the arm between elbow joint and wrist joint but the cubit is length from tip of elbow to the tip of the middle finger. so forearm length is smaller than the cubit. So answer is option C

D is only correct and not A. So, A is the correct answer

Ans 11:

sudeep from DPS, Bangalore
Class : Class 8
kelvin is the SI unit of temperature so option D is correct and A is also correct because rectilinear motion is motion in a straight line like a car moving on a straight road

Ans 12:

Vidwat Amal from Podar International School , Anand
Class : Class 8
why A is correct and not incorrect because a vehicle need not go in rectilinear path on a straight road it can go zigzag as well
