Is it true that the Else branch must contain a condition within its square brackets?

The statement is false because the Else branch in a conditional structure does not require a condition within its square brackets. The primary function of the Else branch is to provide an alternative action when the condition in the If statement evaluates to false. It operates as a catch-all for scenarios that are not specifically addressed by the preceding If or Else If conditions.

Since the Else branch itself does not require an evaluation of a condition—it simply executes its block of code when the earlier conditions are not met—it is independent of any conditions. Other options may suggest varying requirements or conditions under different settings, but the essence of the Else branch remains constant across standard programming paradigms: it acts without needing a further condition.
