Given below are two statements, one labelled as Assertion (A) and the other labelled as Reason (R) :

Assertion (A) : The Raster format data structure provides a greater computational efficiency.
Reason (R) : The Raster format data is simple.
In the context of the above two statements, which one of the following is correct ?

  • A.Both (A) and (R) are correct and (R) explains (A).
  • B.Both (A) and (R) are correct but (R) does not explain (A).
  • C.(A) is correct, but (R) is false.
  • D.(A) is false, but (R) is correct.

Answer: C

Assertion (A) is accepted as correct in the key, as raster data processing, such as overlay and map algebra, is computationally efficient. Reason (R) is false: raster data are simple in structure, but the key does not accept this as a true reason for the efficiency, treating the statement as incorrect. So the key gives that (A) is correct but (R) is false, which is code C. Code A and B accept the reason, and code D rejects the assertion.
