Explanation:

The following extract from the second paragraph mentions, “Moreover, corporations, driven by the profit motive, will necessarily tend to underplay, if not ignore, potential adverse consequences, especially those which are unknown and which may manifest themselves only over a relatively long period.” Therefore, option 2 is given in the paragraph and can be eliminated.
The following extract from the third paragraph mentions, “In our own experience, some of the early high yielding varieties (HYVs) of rice and wheat were found susceptible to widespread pest attacks; and some had problems of grain quality.” Option 3 can also be ruled out. Paragraph 2 also refers to the same problem.
The following extract from the second paragraph mentions, “high-pressure advertising and aggressive sales campaigns by private companies can seduce farmers into accepting varieties without being aware of potential adverse effects and the possibility of disastrous consequences for their livelihood if these varieties happen to fail. There is no provision under the laws, as they now exist, for compensating users against such eventualities.” Hence, there is a need for such provisions under the laws and they need to be addressed. Option 4 can be eliminated as well.
Option 1 is not a consequence since it mentions that ‘Development of newer and newer varieties will lead to increase in biodiversity’ while the passage states just the opposite, i.e. “The larger, longer-term consequences or reduced biodiversity that may follow from the use of specially bred varieties are also another cause for concern.”
Hence, the correct answer is option 1.
