Which of the following best defines the term 'accessible'?

The term 'accessible' is best defined as "easy to reach, obtainable" because it reflects the fundamental idea of something being within reach or available for use. When something is considered accessible, it typically means that it can be easily approached, entered, or obtained by a wide range of individuals without significant barriers. This concept is particularly important in contexts such as education, healthcare, and public services, where accessibility ensures that individuals can participate fully without facing obstacles that may prevent them from doing so.

Other definitions, such as being expensive or available only to certain individuals, introduce limitations that contradict the essence of accessibility. Accessibility implies inclusivity and the absence of unnecessary challenges in obtaining or using resources. Therefore, defining 'accessible' in terms of being easy to reach and obtainable captures its true meaning.
