During heart development which of the following represent the correct temporal events in morphogenesis?
a. formation of the linear heart tube, formation of second heart field, septation, and looping.
b. formation of heart primordia, formation of the linear heart tube, looping, and septation
c. septation, looping, and formation of second heart field.
d. formation of second heart field, septation, specification of the cardiogenic mesoderm.

The correct answer is option B.

Explanation:

A biological procedure, which makes an organism to form its shape is known as morphogenesis. It is one of the basic features of developmental biology along with the control of cellular differentiation and cell growth. The procedure monitors the organized spatial arrangement of cells at the time of the embryonic development of an organism.  

During the development of heart, the formation of heart primordia takes place during the first trimester of pregnancy, after that the formation of endothelial heart tubes takes place, then looping, and in the end septation occurs.
