Option A: Should not is the full form, but the question asks for the contracted form.
Option B: Correct. Shouldn't is the contraction of should not and properly negates the suggestion.

Explanations: The sentence "You mustn't forget that you have to buy Megan a present for her birthday!" is incorrect because the verb "must" implies an absolute necessity, which does not fit the context of reminding someone about a task they should remember. The correct form using "ought to" would be: "You ought to remember that you have to buy Megan a present for her birthday!"

Option Analysis:

Option A: Ought not to - Incorrect, as it uses "ought not," which is less common and awkward in this context.

Option C: "Don't ought to" is also grammatically incorrect as "ought to" does not have a contraction form in its negative.
Option D: "None of the above" is incorrect since option B is correct.

19. My mom says that I ..... leave my bike on the street because it might get stolen

Explanations: "Mustn't" is the correct answer because it conveys a strong prohibition, indicating that leaving the bike on the street would be highly inappropriate and potentially dangerous according to your mother's advice. This aligns with the context of caution about theft.
