Statement 1:
"An execution plan is a blueprint for evaluating a query and is usually represented as a tree of relational operators".
This statement is true. Since the execution plan of a query is the most efficient way of executing in that machine according to the optimizer.
Statement 2:
"A database management system will always be efficient as compared to a file system".
This statement is false. Consider the example for the operation/manipulation of text data that is not supported by DBMS then performing those operations/manipulations will be easier on the file system rather than with DBMS.
Hence, the correct options are (A) and (D).
