This decision control structure enables the program to execute a statement or block of codes if and only if the Boolean expression is true

Select one: a. Both if-then and switch b. switch c. if-then d. Neither if-then and switch

Both if-then and switch is the decision control structure that enables the program to execute a statement or block of codes

Explanation:

This decision control structure always checks for one or more condition and execute true statement "if the condition is true" otherwise it will execute false statement (if present). The "true statement" is compulsory.

In case of "if-then loop", it executes the true block only if the Boolean expression is true. In a similar way in switch-case, the same happens and instead of else part there will be a "default" statement which is compulsory to be present and it will get executed.
