When we say that persons are using anecdotal evidence to support their claims,what do we mean

A)  The evidence is not true. 
B)  The evidence is based on social desirability bias. 
C)  The evidence was collected from a variety of sources. 
D)  The evidence is based on personal experiences.

Anecdotal evidence refers to evidence based on personal experiences, rather than on empirical or scientific evidence gathered through a systematic process. While personal experiences can be valuable, they are not always representative or reliable and should not be the sole basis for making conclusions or decisions.
