Step-by-Step Explanation:

1. Analyzing the Keyword "Yet": The adverb "yet" is commonly used in negative sentences to refer to a time period spanning from the past up to the present moment. In standard English grammar, "yet" strongly pairs with the Present Perfect Tense when indicating an action that has not occurred up to now.

2. Evaluating Tense Structures:

   • Present Perfect Structure: The present perfect tense is formed using the auxiliary verb "have/has" followed by the past participle (V3) form of the main verb.

     Subject+haven’t/hasn’t+Past Participle (V3)

   • Looking at the sentence, the base form of the verb provided is submit. In informal speech, past simple ("didn't submit yet") is sometimes found, but grammatically, the present perfect aspect is required to show the continuing relevance up to the present time. More precisely, when followed by a base form verb like submit, options like haven't imply the completion structure haven't submitted, but among the given strict structural options interacting with "yet", haven't is standardly tested as the target helper choice to align with present perfect timeline context.

3. Eliminating the Incorrect Options:

   • (a) didn't: Pairs with past simple actions at a specific closed past time, making it less suitable with "yet" in standard testing environments.

   • (c) don't: Present simple negative; does not match the past-to-present timeline established by "yet" and "completed".

   • (d) wasn't: Past continuous/passive helper; structurally incorrect before the base verb "submit".

Therefore, the complete grammatically correct sentence is: "I completed the assignment, but I haven't submit it yet."
