CUET-PG 2023 Shift 2 Question 86: Matrices, determinants and linear systems

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R. Assertion A: For matrix A=[12816]A = \begin{bmatrix}1 & 2\\8 & 16\end{bmatrix}A=[18​216​], rank of A = r(A) = 1. Reason R: For matrix A if ∣A∣=0|A| = 0∣A∣=0, then it implies that rank of matrix A given by r(A) is less than full rank. In the light of the above statements, choose the most appropriate answer from the options given below:

Plain-text version

Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R. Assertion A: For matrix A = [1 2; 8 16], rank of A = r(A) = 1. Reason R: For matrix A if |A| = 0, then it implies that rank of matrix A given by r(A) is less than full rank. In the light of the above statements, choose the most appropriate answer from the options given below: (A) Both A and R are correct and R is the correct explanation of A (B) Both A and R are correct but R is NOT the correct explanation of A (C) A is correct but R is not correct (D) A is not correct but R is correct
