The correct options are
A Commercial farming is well organised near well-developed and densely-populated areas.
B Southern European countries are more involved in livestock farming and growing fruits and vegetables.
D West European countries practice mixed farming.
The European continent has a vast, level, fertile, and well-irrigated land. The prevailing climatic conditions are favourable for agriculture. Mixed farming is practised in west European countries. The agriculture is commercial and well-organised near densely populated urban areas. On the whole, less than 10% of the people in Europe are engaged in agricultural activities. Because of the Mediterranean climate in southern Europe, livestock farming and fruit and vegetable farming are common in that region.
