Task: Class Definition Understanding (ontology: Sciences/Computer_Science)

Which of the following definitions best describes 'R software'?

A. This package was developed to simplify the use of Bioconductor tools for beginners having limited or no experience in writing R code. This library provides a graphical interface allowing QC, filtering, statistical validation, and alternative splicing analysis.
B. This package implements various algorithms for inferring mutual information networks from data. All the algorithms compute the mutual information matrix in order to infer a network. Several mutual information estimators are implemented.
C. Statistical methods for identifying differentially expressed genes in replicated cDNA microarray experiments.
D. The purpose of this package is to provide a comprehensive and easy-to-use tool for quality assessment and to identify differentially expressed genes in the Affymetrix gene expression data.

Answer: Statistical methods for identifying differentially expressed genes in replicated cDNA microarray experiments.
