Explanation:
Some of the major drawbacks of modelling fishing are as follows –
a) The fixed quota model is very risky as a miniscule change in attributes can result into extinction of fish.
b) On the other hand fixed effort harvesting can decrease the risk of fish population extinction
Hence, option A is correct
