The correct answer is C. Clavicle and scapula
Explanation:
The pectoral girdle, also called the shoulder girdle refers to a set of bones that connect the arm to the rest of the skeleton. In human beings and many other species, the pectoral girdle consists of the clavicle that is a long bone that goes from the shoulder to the sternum and the scapula that is a flat bone and goes from the upper zone of the arm to the clavicle. Additionally, in some species, the shoulder girdle includes a third bone called coracoid.

Answer:
Molecules can be made of one type of element pr a mixture of element.
Molecule is two or more atoms bonded together.
Compound act like a different substance (because have different properties from its constituent elements).
Explanation:
A molecule is the combination of one or more atoms. These atoms may be from different elements are of the same elements. All the compounds are molecule but not all the molecules are compound. For example,
H₂O is a water molecule and also a compound. H₂ is just a molecule not a compound because both atoms are from same element.
The compound have different properties from its constituent elements. e.g water is compound made up of hydrogen and oxygen. Hydrogen is flammable gas and oxygen support combustion, while water doesn't have these properties. However in mixture elements retain their own properties that's why mixture is different from the compound.
