Answer:
The correct answer is "gerund"
Step-by-step explanation:
A gerund is formed by verb+ing and always acts as a noun in a sentence.
In this case, the gerund is "wishing" and it is the noun and subject of the sentence.
The rest of the options are incorrect since an infinitive is formed by verb+to (To swim). A present participle is formed by verb + ing but functions as an adjective instead of a noun (breaking news).
