Let \( A = \{1, 2, 3, 4, 5, 6, 7, 8, 9, 10\} \) and \( B = \{2, 3, 5, 7\} \). Which of the following sets represents \( A \cap B \)?→Let \( A = \{x \in \mathbb{N} : x \le 50 \text{ and } x \text{ is a multiple of } 3\} \) and \( B = \{x \in \mathbb{N} : x \le 50 \text{ and } x \text{ is a multiple of } 5\} \). The number of subsets of \( A \cap B \) is:→Given below are two statements: Statement I: The empty set \( \phi \) is an infinite set because it contains no elements to count. Statement II: Two finite sets are equal if and only if they have the same number of elements. In the light of the above statements, choose the most appropriate answer from the options given below:→Given below are four statements for any three sets \( A, B, \) and \( C \): (A) If \( A \in B \) and \( B \subset C \), then \( A \subset C \). (B) If \( A \subset B \) and \( B \in C \), then \( A \in C \). (C) If \( A \subset B \) and \( B \subset C \), then \( A \subset C \). (D) If \( A \not\subset B \) and \( B \not\subset C \), then \( A \not\subset C \). Choose the correct statement(s) from the options given below:→
