Correct Answer

✅ Option a — (2,5),(3,5)\displaystyle (2,5), (3,5)

All Options:

  • A(2,5),(3,5)\displaystyle (2,5), (3,5)
  • B(5,2),(5,3)\displaystyle (5,2), (5,3)
  • C(2,3),(5,5)\displaystyle (2,3), (5,5)
  • DNone of these

Detailed Solution & Explanation

We are given three sets:
A={2,3}\displaystyle A = \{2, 3\}
B={4,5}\displaystyle B = \{4, 5\}
C={5,6}\displaystyle C = \{5, 6\}
First, let us find the intersection of B\displaystyle B and C\displaystyle C (common elements):
B∩C={5}B \cap C = \{5\}
Now, we compute the Cartesian product A×(B∩C)\displaystyle A \times (B \cap C):
A×(B∩C)={2,3}×{5}A \times (B \cap C) = \{2, 3\} \times \{5\}
The Cartesian product is the set of all ordered pairs (a,x)\displaystyle (a, x) where a∈A\displaystyle a \in A and x∈B∩C\displaystyle x \in B \cap C:
A×(B∩C)={(2,5),(3,5)}A \times (B \cap C) = \{(2, 5), (3, 5)\}
Hence, **Option A** is the correct answer.
