Given the following review types and review characteristics: a. Pair review b. Walkthrough c. Technical review d. Inspection 1. Formal 2. Informal 3…

This option correctly matches the review types with their defining characteristics according to the ISTQB syllabus. A pair review (a) is an informal (2) process. A walkthrough (b) is often led by the author to present a work product, gain understanding, and generate new ideas (3). A technical review (c) is a more formal process focused on improving the product quality and can serve as a training opportunity (4). An inspection (d) is the most formal (1) review type, characterized by defined roles, metrics, and strict entry/exit criteria.

A. This option incorrectly classifies a pair review as formal, which is a defining characteristic of an inspection.
B. This option incorrectly classifies a technical review as informal and misaligns the purposes of other review types.
D. This option incorrectly swaps the primary purposes of a walkthrough (generating ideas) and a technical review (training/product improvement).
