The question is in another language so, English translation for the given question is as follows:
It is made up mostly of water; different organic molecules, such as carbohydrates; and inorganic molecules, such as mineral salts. It carries out most of the chemical reactions of the synthesis of molecules and obtaining energy. To which of the following cell structures does the above description correspond? 
a) Nucleus. b) Genetic material. c) Cytoplasm. d) Cell membrane.
Answer:
c) Cytoplasm
Explanation:
The Cytoplasm is defined as a thick solution filled inside each cell and all the organelles float in the cytoplasm.
The Cytoplasm is majorly made up of water, carbohydrates, salts, and proteins. Cytoplasm contains different molecules and enzymes that carries out most of the chemical reactions and obtain energy. Cytoplasm also helps in providing shape to the cell. 
Hence, the correct option is c) Cytoplasm.

i think the answer is B, i may be wrong... because potential energy is stored energy and kinetic energy is energy due to motion so the less potential energy the more kinetic energy 
and mechanical energy means the energy of motion, such as a moving vechile which is using kinetic energy.
