Yom Kippur War was fought between which sides/countries?

The Yom Kippur War (October 1973), also called the October War or the Fourth Arab–Israeli War, was fought between Israel and a coalition of Arab states led primarily by Egypt and Syria. On October 6, 1973, Egypt and Syria launched a coordinated surprise two‑front attack against Israeli positions — Egypt across the Suez Canal and Syria on the Golan Heights — aiming to regain territory lost in 1967 [2]. Contemporary summaries and official histories describe the rapid escalation, great‑power resupply efforts, and subsequent ceasefires/negotiations, consistently identifying Israel versus Egypt and Syria (with allied Arab states) as the combatants; therefore option 3 is correct [3].
