Best Answer Explained in Below-:

The phrase "প্রিয় কথা বলে যে রমণী" translates to "the woman who speaks sweet words." Among the provided options, the key lies in understanding the meanings of the terms that follow.

1. **প্রিয়ভাষিনী (Priyabhāṣinī)**: This term means "one who speaks with affection," focusing on the nature of the speech rather than the individual character.

2. **সাদালাপিনী (Sādālapinī)**: This term implies a woman who speaks plainly or simply, which does not necessarily convey sweetness in conversation.

3. **প্রিয়ংবদা (Priyaṅbadā)**: This term translates to "the one with sweet words" or "who speaks lovingly." It encapsulates the essence of the phrase perfectly, referring directly to someone who speaks in a beloved and endearing manner.

4. **প্রিয়ংবদিনী (Priyaṅbadinī)**: While this could also suggest endearing speech, it is less commonly used and may not have the same immediate recognition or understanding as "প্রিয়ংবদা."

Thus, "প্রিয়ংবদা" clearly aligns with the description of someone who is characterized by speaking sweetly and lovingly, making it the most fitting choice for the question asked.
