The correct option is B The major social groups in Sri Lanka are the Sinhalese and Tamilians.
Sri Lanka is an island nation off the coast of India. Two major groups inhabit this island nation- the Sinhalese and the Tamilians. After its independence in 1948, the Sinhalese wanted to establish their dominance over the country, which led to the sidelining of the Tamilians. This caused a bloody civil war that ended in 2009.
