In India, red list of plant species is prepared by:
(a) Botanical Survey of India
(b) Forrest department of India
(c) Geological survey of India
(d) Census department of India

Answer 1

The country's apex taxonomic research organization, which is under the Ministry of Environment, Forest & Climate Change, was established under the leadership of Sir George King on 13 February 1890 by the Government of India.

Complete step by step answer:
India's Botanical Survey is a government organization. The key program of the survey is the preparation of a comprehensive account of the country's plant resources in the form of national, regional, and district flora. The new Flora of India in the form of Fascicles for higher plants has begun to be published.
Forest department of India: The key mandate of the service is to enforce the National Forest Policy with a view to ensuring the country's ecological stability through the conservation and participatory management of natural resources in a sustainable manner. The service members also maintain the country's Tiger Reserve (TR), Wildlife Sanctuaries (WLS), and other Protected Areas (PA) National Parks (NP) .
India's Geological Survey is an Indian research agency (1851), a Ministry of Mines organization of the Government of India, one of the oldest such organizations in the world and the second oldest survey in India for geological surveys and studies, as well as the primary provider of basic earth science knowledge to government, industry, and the general public, as well as the official participant in the steel, coal, metals, cement, power and gas industries.
Registrar General and Census Commissioner of India, established in 1961 by the Ministry of Home Affairs of the Government of India, to coordinate, administer and evaluate the results of India's demographic surveys, including the Census of India and the Linguistic Survey of India.
So, the correct answer is ‘Botanical survey of India’.

Additional information: Out of a quarter-million vascular plant species recorded so far, India has an estimated 15,000 species. The Botanical Survey of India (BSI) is involved in the country's plant wealth survey, research, utilization, and conservation.

Note: India's Botanical Survey also offers a Plant Taxonomy Research Fellowship and also offers post-doctoral fellowships to those qualified in taxonomy who want to pursue their research relevant to the BSI mandate.
