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

Which of the following definitions best describes 'Weka'?

A. the concept is an R package designed to facilitate downstream analysis of RNA-seq and similar expression data with various exploratory plots and data mining tools.
B. the concept (Waikato Environment for Knowledge Analysis) is a suite of machine learning software, originally intended for data mining tasks, written in Java and developed at the University of Waikato, New Zealand.
C. the concept, often simply Postgres, is an open source object-relational database management system (ORDBMS) with an emphasis on extensibility and standards compliance.
D. the concept is a software application for simulation and analysis of biochemical networks and their dynamics. the concept is a stand-alone program that supports models in the SBML standard and can simulate their behavior using ODEs or Gillespie's stochastic simulation algorithm; arbitrary discrete events can be included in such simulations. the concept provides an C++ API with language bindings for Perl, python, R, Java, and Octave and is able to communicate with the Systems Biology Workbench the concept carries out several analyses of the network and its dynamics and has extensive support for parameter estimation and optimization. the concept provides means to visualize data in customizable plots, histograms and animations of network diagrams.

Answer: the concept (Waikato Environment for Knowledge Analysis) is a suite of machine learning software, originally intended for data mining tasks, written in Java and developed at the University of Waikato, New Zealand.
