• Pioneering Record of Plant Parasitic Nematodes in India:
• First Report: In 1901, the British botanist and plant pathologist C. A. Barber recorded root-knot nematode (Meloidogyne sp., then referred to as Heterodera radicicola) infesting tea plants in Devala, Nilgiris, South India.
• Significance: This is documented in Indian agricultural records as the very first historical report of a plant parasitic nematode in India.
• Later Nematologists: Das, M.R. Siddiqi, and Dasgupta contributed significantly to nematode taxonomy and survey from the 1950s onward.
• Conclusion: C. A. Barber made the first report of plant parasitic nematodes in India (Option 4).

Correct option: (4) Barber

• Founding of the Journal Nematologica: Nematologica (International Journal of Nematological Research, now published by Brill as Nematology) was founded in Europe under the editorial leadership of P. A. van der Laan and J. H. Schuurmans Stekhoven.
• Publication Year: Although initial organizational meetings and volume preparation occurred in 1956, the journal's official continuous regular issues gained international establishment in 1958.
• Conclusion: Nematologica was officially started in 1958 (Option 1).

Correct option: (1) 1958

• Nathan Augustus Cobb (1859–1932):
• The Father of Nematology: Dr. N. A. Cobb was an eminent American biologist renowned worldwide as the foundational pioneer and 'Father of Nematology'.
• Birthplace: Cobb was born in Spencer, Massachusetts, USA on June 30, 1859. He later served as the Chief of the Division of Nematology at the United States Department of Agriculture (USDA) in Beltsville, Maryland, describing over 1,000 nematode species and inventing foundational nematological equipment (e.g., Cobb's sieving and gravity method).
• Conclusion: N. A. Cobb was born in the USA (Option 3).

Correct option: (3) USA
