Question

Choose the option that correctly punctuates the sentence:

The proposal which was submitted last week however requires further revision

1. A. The proposal, which was submitted last week however, requires further revision
2. B. The proposal which was submitted last week, however, requires further revision
3. C. The proposal, which was submitted last week, however requires further revision
4. D. The proposal, which was submitted last week, however, requires further revision (Correct answer)

Correct Answer

Option D — D

Detailed Solution & Explanation

The correct answer is Option D.

Key Points

• 'The proposal, which was submitted last week, however, requires further revision.'
• The sentence has a non-defining relative clause ('which was submitted last week') and a conjunctive adverb ('however').
• Both must be set off by commas on both sides:
• the relative clause needs a comma before 'which' and after 'week';
• 'however', used as an interrupter, needs a comma before and after it.
• Only option D places all four commas correctly.
• The other options each drop one of the required commas.

Exam Tip

• a non-defining clause (extra information) is always enclosed in commas; a defining clause (essential information) takes no commas.

Additional Information

• A non-defining relative clause — one that adds extra rather than identifying information — is enclosed in commas and introduced by *which*, never *that*.
• A defining clause takes no commas and may use *that*: *The proposal that was submitted last week requires revision* identifies which proposal.
• A sentence adverb such as however is likewise set off by commas on both sides when it sits mid-sentence.
