The true statement regarding T accounts is:
Debits are on the left, and credits are on the right.
T accounts are a fundamental tool in accounting that visually represent how transactions affect individual accounts. Each T account consists of two sides: the left side for debits and the right side for credits. The other statements are incorrect because T accounts can represent all types of accounts, not just assets, and they reflect increases and decreases in a single account, not for multiple accounts at once.
