Crossing over occurs at the four-strand stage when two homologous chromosomes, each consisting of a pair of sister chromatids, are paired. Each crossover involves just two of the four strands and generates two recombinant strands.

The cell wall is what gives plant cells their shape. The cell wall, not to be confused with the cell membrane, is a rigid structure made up of long cellulose fibers, branching hemicellulose fibers, and pectin. The fluid pressure inside the cell also contributes somewhat to their shape.
Answer:
Option D, None of the above
Explanation:
Latent heat of fusion is the amount of energy required to change the phase of metal from solid to liquid. While Latent heat of vaporization is the amount of energy required to change the phase of metal from liquid to gas.
Now, in the question the unknown metal melts from solid to liquid when
of energy is supplied.
None of the metal in the given set of options has "
metal Latent heat of fusion" equal to or near to 
Thus, option D is correct.
