Step 1: Understand the idea:
The sentence talks about finishing a job within a fixed time.
We need the word for a fixed date or time by which work must be done.
Step 2: Recall the concept:
A deadline is the last date or time by which a task must be finished.
Setting deadlines is a key part of self-management and time management.
It keeps a person focused and helps to complete work on time.
Step 3: Check option (C) deadlines:
Deadlines give a time limit to each task. So the sentence reads correctly: set deadlines to get the job done within a specified time limit.
Step 4: Why the other options are wrong:
Areas are places or fields of work. They do not set a time limit.
Plans show what to do and how, but a plan alone does not fix a date.
Standards show the quality expected. They do not fix the time.
Final Answer:
The correct word is deadlines, which is option (C).
