Answer: It is balanced for oxidation state but is not balanced for number of atoms.

Reason: Left: H2 (2 H) and O2 (2 O). Right: 2 H+ (2 H) and only one O2− (1 O) — oxygen atoms are not balanced (2 vs. 1). Oxidation numbers: H goes 0 → +1 (total +2), O goes 0 → −2 (total −2), so the net change in oxidation state (electrons) is zero — oxidation states are balanced.
