Concept:Agricultural extension aims to educate and support farmers, but certain limitations can hinder its reach and become a disadvantage.
Explanation:Agricultural extension services are meant to train farmers, introduce improved techniques, and increase productivity.
However, a key potential disadvantage is the lack of access to these services in remote areas.
In such places, extension agents may be few, roads may be poor, and communication systems may be limited.
Consequently, farmers in these areas miss out on vital information and modern farming methods.
This creates an uneven spread of knowledge, leaving remote farmers behind.
Options B, C, and D are all positive benefits of agricultural extension, not drawbacks.
Only option A correctly identifies a genuine limitation or downside of the extension system.
Thus, the disadvantage is the inability of extension services to reach every farmer, especially those in isolated communities.
Answer:A. Lack of access to extension services in remote areas
