Select differences between reference type and value type: i. Memory allocated to ‘Value type’ is from heap and reference type is from ‘System. ValueType’ ii. Memory allocated to ‘Value type’ is from ‘System. ValueType’ and reference type is from ‘Heap’ iii. Structures, enumerated types derived from ‘System.
