ASSERTION (A) : Area sampling by random numbers requires the area under study which should be gridded within two areas at right angle.

REASON (R) : The intersections of row and coulmn of the area will give the sample locations of observations in the area.

• Both (A) and (R) are true and (R) is the correct explanation of (A).

• Both (A) and (R) are true but (R) is not the correct explanation of (A).

• (A) is true , but (R) is false. 

• (A) is false , but (R) is true.
