Answer
Answer: (A) sodium alginate and dropping it in a solution of calcium nitrate
Explanation: Hydrated synthetic seeds are created by mixing somatic embryos with sodium alginate and then dropping the mixture into a calcium nitrate solution, which helps form a gel around the embryos. The other options involve incorrect reagents or solutions.
