Solution
Ontology engineering
It is a field which studies the methods and methodologies for building ontologies, which encompasses a representation, formal naming and definition of the categories, properties and relations between the concepts, data and entities.
Taxonomy hierarchy
A taxonomy in computer science is a method for organizing data. In such a taxonomy, different pieces of information are stored along with their relationships to other data in the taxonomy. This produces a hierarchy of data, which makes it easier for programmers and users to compute certain information.
Inheritance
Inheritance means one class can inherit properties and behavior of another class. This is one of principle of OOPs (Object Oriented Programming).
Probability model
A probability model is a mathematical representation of a random phenomenon. It is defined by its sample space, events within the sample space, and probabilities associated with each event.
Therefore,
(A) Ontological Engineering - (IV) Representing concepts, events, time, physical concepts of different domains
(B) Taxonomy Hierarchy - (II) Organizing knowledge into category and subcategory
(C) Inheritance - (I) Organizing subclass relations
(D) Probability model - (III) Attaches a number with each possibility
Hence, the correct answer is option 3.
