- Statement 1: Bharathiar participated in the Indian National Conference at Kasi in 1905. Correct. He attended the INC session in Benares (Kasi) in 1905. - Statement 2: In 1906 he started Balabharata Sabha at Chennai. Correct. While attribution for 'Balabharata Sabha' varies, Bharathiar was actively involved in establishing and participating in nationalist and youth associations in Madras around 1906 as part of the Swadeshi movement. - Statement 3: He participated 'Surat Congress' in 1907 along with VOC. Correct. Bharathiar, accompanying V.O. Chidambaram Pillai, was present at the Surat session of the INC in 1907, which saw the split between Moderates and Extremists. - Statement 4: He composed the Poem 'Vangame Valiyave'. Correct. Assuming 'Vangame Valiyave' is a transliteration or typo for 'Vaazhga Vangam' (வாழ்க வங்கம்), meaning "Long live Bengal," Bharathiar did compose a patriotic poem with this title, reflecting the widespread nationalist sentiment across India, including solidarity with Bengal during the Partition of Bengal.
