Which observation Sid, the science to see as most promising for developing a testable hypothesis that helps determine the connection between organize farming in biodiversity

A 12 different fish species were observed in a small pond
B. An enormous
C. Twelve one different

species of plants were found in a field where organic farming was being practiced.

D. A decrease in the population of bees was observed in an area where conventional farming practices were being used.

Based on the information provided, observation A is the most promising for developing a testable hypothesis that helps determine the connection between organized farming and biodiversity.

Observation A states that 12 different fish species were observed in a small pond. This observation suggests that there may be a correlation between organized farming practices and biodiversity. The hypothesis could be that organized farming practices (such as regulated pesticide use, efficient waste management, or habitat preservation) positively impact the diversity of fish species in the pond.

Observation B, about an enormous something, does not provide any specific information related to organized farming or biodiversity.

Observation C, about twelve one different something, seems incomplete and lacks relevant information that can be used to develop a hypothesis related to organized farming and biodiversity.
