d. Fractal foam

Answer 1

1. Correct option is B. Pixel Oriented Techniques is a recursive pattern technique which is based on visualizing larger data sets. It analyses large and multidimensional data sets.

2. The correct option is B. It uses Scatter plot matrix and indicates the fraction of solid material on anywhere on the design page.

3. Option D is correct. Icon based Techniques use Chernoff faces which help in revealing the trends in the data and makes it easy to understand.

4. Option A is correct. It is a Dimensional stacking. It is a traditional text mining technique which uses apriori paradigm for finding relevant subgraphs.
