In Sanskrit, 'aṅga' (अङ्ग) means 'limb', 'part', 'body', 'component', or 'constituent part'. It refers to a part or portion of something whole. While it could metaphorically mean 'wings' as body parts, 'part of' is the most direct and general translation. The ancient kingdom of 'Aṅga' (option A) exists historically, but as a common noun, the word means part/limb.
