Synonym cluster completion: “Release : Liberate : Emancipate” — select the option that belongs to the same core meaning set.

Introduction / Context:
The trio “Release, Liberate, Emancipate” forms a synonym set centered on the idea of setting free. The correct completion should align in meaning with this core sense rather than introducing a different legal or contextual nuance.

Given Data / Assumptions:

• The stem words point to removing restraint or granting freedom.
• We require a direct, general synonym.

Concept / Approach:
Among the options, “Free” precisely captures the same action/state. “Pardon” is legal forgiveness (may not physically free someone), and “Quit” is to leave/stop; “Ignore” and “Restrain” are semantically off-target.

Step-by-Step Solution:
1) Identify the shared semantic core: remove restraint.2) Choose the simplest direct synonym: Free.3) Exclude words with adjacent or unrelated meanings.

Verification / Alternative check:
Dictionary cross-checks confirm “liberate = set free,” “emancipate = set free from restrictions,” which directly map to “free.”

Why Other Options Are Wrong:

• Pardon: Legal/forgiveness context; not necessarily release.
• Ignore: No relation to freeing.
• Quit: To stop/leave; not to free another.
• Restrain: Opposite notion of freedom.

Common Pitfalls:
Equating “pardon” with “free” in every context; pardons may remit guilt but do not always imply immediate physical release.

Final Answer:
Free
