Best Answer Explained in Below-:

The phrase "I would rather die ____" is completed correctly by the option "than beg" (B) due to the structure of comparative expressions in English. The construction "would rather" is used to express a preference between two options, and it typically pairs with an infinitive verb form, which in this case is "to beg." However, in common usage, the phrasing often simplifies to "rather...than" followed by the base form of the verb.

Option B, "than beg," is correct because it directly compares the act of dying with the act of begging, implying a strong preference against begging. The form "than beg" is grammatically parallel, following the structure of "would rather" to indicate a choice.

In contrast, the other options do not fit the grammatical structure or intended meaning:
- "to beg" (A) disrupts the comparative structure.
- "than begging" (C) uses the gerund form, which is less common in this comparison.
- "than would have begged" (D) misrepresents the tense and also complicates the preference being expressed.

Therefore, "B) than beg" is the clear and grammatically sound choice, effectively conveying the speaker's strong preference.
