The civil war in Sri Lanka since 1983 can be attributed to which one of the following reason?

Linguistic reasons

The correct answer is Option 1: Linguistic reasons.

Reason: The civil war in Sri Lanka, which began in 1983, was largely rooted in the denial of the linguistic rights of the Tamil minority by the Sinhala-speaking majority. The adoption of Sinhala as the sole official language and the resulting discrimination against Tamils intensified ethnic tensions, eventually leading to civil war.

NCERT: "The civil war that has raged in Sri Lanka since 1983 is partly based on the denial by the majority linguistic group of the rights of the minority. Another of India’s neighbours, Pakistan, was divided in 1971 because the Punjabi and Urdu speakers of its western wing would not respect the sentiments of the Bengalis in the east. ".
