Photosynthesis uses radiant energy from light converting it into . The process requires light, water, and to produce sugars. Oxygen is a byproduct. Life on earth depends on photosynthesis.

Explanation:

Photosynthesis is the process through which plants, some bacteria, and some others organisms  made their food by the use of  energy from sunlight and convert it into chemical energy to  produce sugar. The conversion of sunlight energy into usable chemical energy, is held by chlorophyll. The photosynthetic process uses water  as an electron donor and releases the oxygen.

The overall reaction of photosynthesis is:

6 molecules of water + 6 six molecules of carbon dioxide with the help of light, produce one molecule of sugar + six molecules of oxygen

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
