With reference to the invaders in ancient India, which one of the following is the correct chronological order?

The correct chronological sequence is Greeks → Sakas → Kushans. After Alexander’s campaigns, Greek (Indo-Greek/Bactrian) settlements and kingdoms were established in north‑western India (the Indo‑Greeks) and persisted into the 2nd–1st centuries BCE [2]. The Śakas (Indo‑Scythians) invaded and established rule in the north‑west after the Indo‑Greeks, rising from the latter part of the 2nd century BCE and remaining influential until the coming of the Kuṣhāṇas [1]. The Kushāṇas (Yuezhī/Tocharians) established their power subsequently, supplanting earlier groups and forming a major empire in the early centuries CE [3]. Thus the chronological order in the options is option (1).
