See explanation

Explanation:

In the section A,B

C triple bond O has a higher bond energy. A triple bond is shorter and more difficult to break hence they have a higher bond energy.

For the same reason in the C,D section; C triple bond N has a higher bond energy.

In the next section, the higher the bond order the shorter the bond. Hence C triple bond C is the shortest in the A,B section while C triple bond O is the shortest in the C,D section. Both have a bond order of 3.

In the A,B section; I is larger than Br hence H-Br has the shortest bond length.

In the C,D section; Br is larger than Cl hence P-Cl has the shortest bond length.

Answer: D

Explanation: Physical science is the study of the inorganic world. That is, it does not study living things. (Those are studied in biological, or life, science.) The four main branches of physical science are astronomy, physics, chemistry, and the Earth sciences, which include meteorology and geology.
