Topic: Conjugation of Verb,

Best Answer Explained in Below-:

The verb "spread" is an example of an irregular verb, meaning that it does not follow the regular pattern of adding "-ed" to form its past tense and past participle. In English, the past participle is used in various grammatical constructs, such as perfect tenses and passive voice.

The correct answer, option D) "spread," serves as both the simple past tense and the past participle of the verb. For instance, in the sentence "He has spread the news," "spread" is the past participle used with the auxiliary verb "has." This usage is crucial for forming present perfect tense, which indicates an action that happened at some indefinite time in the past but is relevant to the present.

In contrast, option A) "spreaded" is incorrect because "spread" does not adopt the regular "-ed" form. Option B) "spreading" represents the present participle and is used in continuous tenses, while option C) "spreed" is not a recognized form of the verb. Therefore, understanding the irregular nature of the verb "spread" solidifies why "spread" is the accurate choice for both past tense and past participle forms.
