What are the present, past, and past participle forms of 'swim'?

• A. Swim, Swam, Swum
• B. Swim, Swum, Swam
• C. Swims, Swam, Run
• D. Swim, Swam, Swim

Answer: (A)

The main idea here is knowing the forms of an irregular verb: base present, past tense, and past participle. For swim, the base form used for present tense with I/we/you/they is swim. The past tense is swam, which shows a vowel change from the base form. The past participle is swum, and you’ll see it with have/has/had in perfect tenses, like I have swum in the lake. So the sequence Swim, Swam, Swum fits exactly the three forms in the order asked. Other options mix up these forms or use the wrong form entirely. For example, swims is the third-person singular present form, not the base present. Run is a different verb altogether. Swum as the past tense is incorrect because swum is used only with have/has/had.
