Final answer:

Observation is the least flexible survey method due to the limitations imposed by the researcher's presence and the potential influence on subjects' behaviours.

Step-by-step explanation:

Considering the flexibility of various survey methods, observation is likely the least flexible. Unlike surveys conducted by telephone, mail, or online, which can be structured to reach a wide and diverse population relatively easily, observation as a research method requires the researcher to be present in a specific location and time to observe behaviours. This method is constrained by the researcher's ability to be in multiple places at once and may also be limited by the context in which observations can be made without influencing the subjects' behaviours. Additionally, observation does not allow for the collection of a large amount of data that surveys can often provide. Moreover, issues such as ethical considerations and the presence of the observer potentially affecting the behavior being studied can further limit the flexibility of this method.
