Accrued rent for unpaid period post-31 March Steps:

• Opening $600 accrual covers prior period up to 30 June; first payment$900 on 28 July settles this plus July rent ($300/month rate from$900/3 months).
• Second payment $1200 on 11 November covers rent up to 31 March (4 months at$300/month).
• From 1 April to 30 June, 3 months' rent incurred but unpaid.
• Accrual = 3 months × $300/month =$900. Why C is correct:
• Per accrual accounting, expenses incurred but unpaid at period-end are recorded as liabilities; here, April-June rent matches this definition for $900. Why the others are wrong:
• A: Opening $600 ignores settlements and new unpaid periods.
• B: No prepaid asset exists; payments end before year-end.
• D: No overpayment beyond 30 June; post-March rent creates liability, not asset.

Final answer: C
