When energy changes from one form to another, it is called energy A. radiations
B. transmissions
C. solutions
D. transformations

(see below)

Explanation:

Using the process of elimination:

It's not energy radiations because radiation is a way energy is transferred.

It's not energy transmissions because that's the transfer of energy from one medium to another, like the sun to a black construction paper through radiation. There are three ways of transmission: radiation, convection, and conduction.

It's not solutions because a solution is a homogenous mixture where it is uniform in composition and appearance throughout. Also, the term "energy solutions" makes no sense whatsoever.

It's most likely energy transformations because energy transformation, also called energy conversion, is the process of changing energy from one form to another.

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.
