What is the default value of Available in Field?

• A. No
• B. Yes
• C. Undefined
• D. Null

Answer: (A)

The default value for a boolean field like Available is usually false, represented as No. This reflects the idea that, unless you actively mark something as available, it should be treated as not available. It avoids ambiguity and matches how checkboxes work: an unchecked box corresponds to a false/default No state.

Why the other options don’t fit as the typical default: Yes would mean it’s available by default, which isn’t the common assumption for an availability flag. Undefined or Null would indicate the field has no value set at all, which is only appropriate if you need a separate unknown state; for a straightforward yes/no flag, a definite default of No keeps the data clear and consistent.
