They are unicellular ( made up of one cell) prokaryotes ( lacking nucleus and membrane bound subcellular organelles) belonging to the kindom, Archea. They are found in extremely harsh environmental conditions such as hotsprings, boiling mud surrounding volcanoes.

The whiff of the perfume of Tammy reached the nostrils of Jim through the process of diffusion. The process of diffusion can be defined as the process by which the substances (liquid and gases) move from one place to another from the area of high concentration to the area of lower concentration. The particles of the perfume move from the Tammy's body (high concentration) towards Jim through the air (low concentration).
Hence, the answer is 'Option B - diffusion'.
