What is the default initialization value for a boolean field in a class?

  1. true

  2. false

  3. 1

  4. null

The correct answer is: false

When boolean fields are declared in a class without an initial value, they will be automatically initialized to the "false" value. For this reason, choice B is the correct answer. A, C, and D are incorrect because they do-not represent the default initialization value for boolean fields in a class. Choice A is a possible value, but is not the default. Choice C is a numeric value and not a boolean value, and choice D is used for object types and not boolean primitives. Therefore, B is the correct choice.
