Introduction:
This item tests article usage with a singular count noun preceded by a specifying adjective.

Given Data / Assumptions:

• Time-bound phrase "within ... deadline".
• Adjective "stipulated" specifies a particular deadline.
• Count noun "deadline" is singular.

Concept / Approach:
Singular count nouns referring to a specific, known entity require the definite article "the": "within the stipulated deadline".

Step-by-Step Solution:
1) Identify head noun: deadline (singular, countable).2) Adjective "stipulated" signals specificity.3) Insert article: "within the stipulated deadline".

Verification / Alternative check:
If the deadline were generic or plural, article choice might vary; here it is specific.

Why Other Options Are Wrong:
A–C: All are grammatically sound and idiomatic.

Common Pitfalls:
Omitting "the" before singular count nouns modified by specifying adjectives.

Final Answer:
D (Insert "the")
