Answer:
B). The diary entry would have a more casual tone.
Step-by-step explanation:
A diary entry is elucidated as the informal journal where an individual expresses the significant events took place in his/her life along with a blend of personal thoughts, opinions, or feelings associated to it while an article is exemplified as an objective yet a formal expression of a specific event or subject for general interest.
As per the question, a diary entry would differ in tone and expression from the given article while comparing the battery chargers. A 'diary entry would adopt a more casual and personal tone' to describe them along with a touch of author's personal thoughts or feelings(through the use of more descriptive words) about these chargers which is contradictory to the formal and objective tone adopted in the article('The most common complaint about rechargeable batteries is poor performance') to present a factual description for general interest. Thus, option B is the correct answer.
