Option (B)
Explanation:
For an organism to get preserve and form fossil, the organism must be comprised of a hard part and they should be immediately buried by the sediments after their death. The body of the organism must be detached from the oxygenated environment so that the body does not get damaged.
Mudflats usually refers to the coastal wetland areas that are commonly formed in the inter-tidal zone. They are also considered as the tidal flats. These mudflats are comprised of fine sediments that are carried from other places and are rich in organic matter and there is low or absence of oxygen. This helps in the preservation of fossils.
For example, clams with calcite shells that lived on the mudflat are most likely to be preserved in geological history.
Hence, the correct answer is option (B).

Green revolution, great increase in production of food grains (especially wheat and rice) that resulted in large part from the introduction into developing countries of new, high-yielding varieties, beginning in the mid-20th century. Its early dramatic successes were in Mexico and the Indian subcontinent. The new varieties require large amounts of chemical fertilizers and pesticides to produce their high yields, raising concerns about cost and potentially harmful environmental effects. Poor farmers, unable to afford the fertilizers and pesticides, have often reaped even lower yields with these grains than with the older strains, which were better adapted to local conditions and had some resistance to pests and diseases.
