Answer:
Option A is correct.
Element E is Calcium.
Explanation:
On combustion in air, element E forms a solid, white oxide which turns red litmus paper blue.
Turning a damp red litmus paper blue, shows that the oxide of element E is basic as only basic/alkaline substances turn red litmus paper blue.
Only metals, group I and group II metals form basic/alkaline oxides.
Amongst the options provided, only Calcium is a metal, and it is a well known group II metal too at that, hence, it is the correct option
Hope this Helps!!!
The element E oxide that has been able to turn damp red litmus paper blue has been Calcium. The correct option is A.
The burning of an element has resulted in the formation of the oxide of the element.
The oxide turns red litmus paper blue. The bases have the ability to turn red litmus paper blue. Thus the formed elemental oxide has been alkaline in nature.
Thus the formed metal oxide has been belonging to Group I or Group II. From the given elements, Calcium has been the element belonging to Group II, thus the element to be detected has been Ca. Thus option A is correct.
