Solution:Khasa Subba Rao had major journalistic and editorial associations with Indian Express, Swatantra, Swarajya, and the Free Press Journal, making these options the accurate combinations of his career links.He served in senior editorial positions at the Indian Express and was closely connected with the nationalist weekly Swatantra, which he helped shape.
He also played a significant role in Swarajya, both in its early daily edition and in its later influential weekly form, reflecting his deep involvement in political and ideological journalism.
His connection with the Free Press Journal is also well established through his early professional work. In contrast, options involving National Herald, Forward, or Bombay Chronicle do not have sufficiently strong or historically documented editorial roles.
Therefore, the combination B (Indian Express, Swatantra), D (Swarajya, Free Press Journal), and E (Swarajya, Indian Express) correctly represents his authentic professional associations.
