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

Which of the following definitions best describes ''biocGraph''?

A. This package has been prepared to assist users in computing either a sample size or power value for a microarray experimental study. The user is referred to the cited references for technical background on the methodology underpinning these calculations. This package provides support for five types of sample size and power calculations.
B. This package provides tools for computing and analyzing dependency relationships among R packages. It provides tools for building a graph-based representation of the dependencies among all packages in a list of CRAN-style package repositories. There are also utilities for computing installation order of a given package. If the RCurl package is available, an estimate of the download size required to install a given package and its dependencies can be obtained.
C. This package provides examples and code that make use of the different graph related packages produced by Bioconductor.
