A. FALSE according to definition of address space given in the link. whatever memory used by the overlay comes under the address space of computer "https://en.wikipedia.org/wiki/Address_space".

B. TRUE Optimal binary search tree construction can be performed efficiently by using dynamic programming.
ref: http://www.geeksforgeeks.org/dynamic-programming-set-24-optimal-binary-search-tree/

C. FLASE Depth first search can be used to find connected components of a graph.

D. FALSE Infix + (postfix or prefix) is req. to construct the binary tree uniquely.

i think first is also true as we use overlay to run programms that can't fit completely in memory at the same time hence we swap parts of program
