Alright, so umm seriously the answer should be C also in the question Diagram Y. So, here it is cod liver oil which is semi-liquid = Half liquid and half solid. U can push it a little bit so the answer is C. In the book, it is turmeric powder and the answer is showing B too! I mean powder like seriously. The answer in the book should be D also in the book called Diagram Z. It is POWDER!!!!!!!!!!!!!!!!!!!! Like seriously Powder! They need to understand before writing the question in the book.
