Geometric progression basic properties – UGC NET Question

B is the definition of a GP (constant common ratio). C is true for positive terms when r > 1. D is true for positive terms when 0 < r < 1. A is false (that describes an AP), and E is false (a GP is not generally an AP). Therefore B, C and D only are correct. Option A: Option A is incomplete because it omits D, the key decreasing-case when 0 < r < 1. Option B: Option B is incorrect since it includes E, which falsely claims every GP is an AP. Option C: Option C is correct because it includes exactly the true statements (B, C, D) and excludes A and E. Option D: Option D is wrong because it includes A, which incorrectly describes a GP as having a fixed additive difference.
