Which of the following statements about chickens is an example of artificial selection? A. Humans breed chickens that lay the most eggs to produce offspring that will lay more eggs.

B. Roosters compete with other roosters for the right to breed with the hens and pass on their DNA.

C. Chickens have evolved and lost the ability to fly.

D. Roosters are larger and more colorful than hens to attract a mate.

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.
