The true statements regarding T accounts are:
- T accounts reflect increases and decreases in a single account.
- Debits are on the left, and credits are on the right.
The other statements are not accurate. T accounts are designed to represent individual accounts and track the increases and decreases for those specific accounts. Each T account is used for one account only (asset, liability, equity, revenue, or expense) and does not combine more than one account within the same T account.
