<u>Answer:</u> The correct answer is Option B.

<u>Explanation:</u>

Aufbau principle states that the electron will occupy the lowest energy level first before occupying the higher energy levels.

In filling of electrons, '1s' orbital will be filled first than '2s' orbital because the former has low energy level than the later.

For Example: Filling of electrons in chromium atom.

Chromium is the 24th element of the periodic table and its electronic configuration must be written as: 1s^22s^22p^63s^23p^63d^44s^2

But the actual configuration for this is 1s^22s^22p^63s^23p^63d^54s^1

This configuration is an exception to Aufbau's principle as half filled sub-levels is more stable than other configurations.

Hence, the correct answer is Option B.

Morphology

Explanation:

The shape and pigment of the hairs are the morphological elements of the two hair strands.

Morphology deals with the study of the form and structure of organisms, plants and their components.

  • The shape, size, color, textures, orientation are all morphological elements that can be used to draw biological comparison between things.
  • It also entails the relationship between the structures with each other.
  • Morphology is an expression of the genotypic make up of an organism.
