Best Answer Explained in Below-:

The question "রাগ সংগীতে প্রথম অংশকে বলা হয়-" translates to "What is the first part of a raga in music called?" In this context, the correct answer is 'A) রাগ'.

In Indian classical music, 'রাগ' (rag) refers to a melodic framework for improvisation and composition. It serves as the basis for the entire performance. While the term 'রাগ' can also denote the entire structure, it is also considered the foundational theme within a performance, around which various components are constructed.

On the other hand, 'আলাপ' (alaap) refers to a free-form exposition of the raga, where the artist introduces the notes and nuances without rhythm, contributing to the raga's mood and essence. 'বাদী স্বর' (badi swar) and 'বিবাদী স্বর' (bivadhi swar) are technical terms that relate to the dominant and subordinate notes of a raga, respectively.

In summary, while 'রাগ' is the melodic framework, 'আলাপ' is more about the presentation of that framework. Therefore, the first part of a raga performance is fundamentally identified as 'রাগ', making option A the correct choice.
