Heya Friend,
True Statements with Reasons:-
A). Solid 'A' is undergoing change of state. Reason):- Here at the temperature of 90°C the temperature for solid remains same for some times, it means that at this temperature the Solid is changing its state to liquid.
C). Solid 'A' is Pure substance :- Since the process of rise in temperature of solid throughout all time is same(Straight line not any deviation in the graph), it implies it is a pure substance.
D). Solid 'A' has fixed melting and boiling point. Reason). ---Same as that of (C)----.
Hence correct option is 4). A,C,D.
Hope it helps...
