Arabic conditional particles (أدوات الشرط) are words that introduce a conditional clause, linking a condition to its consequence. The question asks which of the listed words are conditional particles.
إذا (idha) - a conditional particle meaning "if" or "when," used for conditions likely to occur. It governs two clauses: the condition (جملة الشرط) and the answer (جواب الشرط).
إنْ (in) - a conditional particle meaning "if," used for conditions whose occurrence is uncertain. It is a جازمة (jussive particle) that puts both the condition verb and the answer verb in the jussive case.
متى (mata) - a conditional particle meaning "whenever" or "when," combining temporal and conditional meaning.
Since all three - إذا, إنْ, and متى - are conditional particles in Arabic grammar, the correct answer is جميع ما سبق (all of the above).
