To determine the correct adjustment journal entry when rent is received in advance, we need to consider the accounting principles dealing with such transactions. Rent received in advance is a liability for the business as the service (providing premises) has not yet been rendered for that period. Thus, the correct journal entry would accommodate this liability.

Let's walk through the reasoning:

1. When rent is received in advance, it should not be recognized as revenue until the period it covers is complete. Therefore, we initially record it as a liability.
2. The entry to adjust rent received in advance involves decreasing an income account (rent received) and increasing a liability account (rent received in advance).
3. The journal entry should reflect this by debiting the rent received account to reduce the revenue erroneously recognized and crediting the rent received in advance account to create a liability.

Based on the above explanation, the correct journal entry is:

Hence, the correct option is:
Debit rent received account and Credit rent received in advance account.

Let's rule out other options:

• Debit profit and loss account and Credit rent account: This entry would relate to expense recognition or income realization, not adjusting advances.
• Debit rent received in advance account and Credit rent received account: This option would be relevant when the rent period starts, recognizing it as income then.
• Debit rent account and Credit profit and loss account: This typically closes an expense to the P&L, not adjusting rent received in advance.

Thus, the correct journal entry is Debit rent received account and Credit rent received in advance account for ₹2,000 as the adjustment.
