Pie chart interpretation basics – UGC NET Question

Statements A, B, C and E correctly summarise how pie charts work. A states that sector angles reflect relative shares. B is true because a full circle corresponds to 360 degrees. C is correct as pie charts emphasise contribution to a whole rather than precise comparisons between many categories. E is true since the total proportion is fixed at 100%, so increasing one share must reduce some other share. D is false because if the total quantity is known, one can estimate or compute numeric values from the percentages shown. Hence A, B, C and E only are correct.

Option A:
Option A is correct because it includes all the valid properties of pie charts and excludes D, which overstates the limitation of estimating values from them.

Option B:
Option B is incomplete as it omits E and thus fails to stress the compensating changes between categories when one sector grows, which is central to understanding proportions.

Option C:
Option C is wrong because it leaves out A and therefore misses the fundamental encoding rule (angles proportional to shares).

Option D:
Option D is incorrect because it omits B and does not include all the true statements together, so it cannot be correct.
