The name of the restriction enzyme would be <em><u>ara1</u></em>.
Explanation:
Restriction enzymes can be described as enzymes which are responsible for cutting DNA from specific sites. Restriction enzymes are present naturally in bacterias and can be produced artificially as well.
The name of a restriction enzyme is made by deriving it from its genus, species and strain. For example, Aeromonas is the genus name, ranidae is the species name and as it is the first to be isolated so the strain would be 1. Hence, the name ara1 will be given to this enzyme.

Answer:
The correct answer would be d. thymus.
The thymus is a specialized lymphoid organ of an immune system.
It serves as the site for training and maturation of T-lymphocytes or T cells.
It is composed two identical lobes each containing outer region termed as cortex and inner region termed as medulla.
T-cells are first trained and selected in the cortex region via positive selection. In this, T cells which are able to bind to foreign antigens are selected and rest are degraded.
The selected T cells then move in the medulla region where they are selected by negative selection. In this, the T cells which binds to self-antigens are degraded and rest survive to become functional T cells.
