FOR a) change in area and change in magnetic flux
b) there ischange in area and also magnetic flux linked
c) there ischange in magnetic flux linked
d) if wedecrase the cross sectional area of secondary
then resistancedecreases but there is no change in magnetic flux and also nochange in area occupied, hence d is the answer.
