In TDH (task descriptive hierarchy) taxonomy,object is present exactly in both branches is known asSelect one:a.XORb.ANDc.ORd.NOT

Break Down the Problem

1. Identify the components: TDH taxonomy and object presence in branches.
2. Determine the relationship between objects in the given options: XOR, AND, OR, NOT.

Relevant Concepts

1. XOR (Exclusive OR): True if one, and only one, of two branches has the object.
2. AND: True if both branches have the object.
3. OR: True if at least one of the branches has the object.
4. NOT: True if the condition of the object being absent in branches holds.

Analysis and Detail

1. In this scenario, we are looking for a condition where an object is present exactly in both branches.
2. The option that describes the situation where both branches have the object simultaneously is the AND function because it requires both branches to satisfy the condition.

Verify and Summarize

• The AND operation reflects the condition given in the question, where the object is confirmed to be present in both branches.

Final Answer

b. AND
