Question

2) Find a word in the meaning to 'sold", a) purchased b) bought 0 c) brought​

Answer 1

Answer - b) bought

Explanation - Sold and bought do indeed mean the opposite thing. In the case of the blog posts, the posters are probably using 'sold' as an interjection, to mean "you have successfully sold that to me". In other words, it means "you have convinced me of something's worth, and so I am prepared to buy it".
