The correct answer is C. Recurrent Neural Network (RNN).
A Recurrent Neural Network (RNN) is a type of artificial neural network that is commonly used for sequence prediction tasks. RNNs are able to learn long-term dependencies between data points, which makes them well-suited for tasks such as weather forecasting and stock price prediction.
Linear Regression is a supervised machine learning algorithm that is used to predict continuous values. Linear Regression is a simple algorithm that can be easily understood and implemented. However, it is not well-suited for tasks that require learning long-term dependencies.
Random Forest is an ensemble learning algorithm that is made up of a number of decision trees. Random Forests are able to learn complex relationships between data points and are less prone to overfitting than other machine learning algorithms. However, they are not as well-suited for tasks that require learning long-term dependencies as RNNs.
Principal Component Analysis (PCA) is a dimensionality reduction algorithm that is used to reduce the number of features in a dataset. PCA is a linear algorithm that does not take into account the order of the data points. Therefore, it is not well-suited for tasks that require learning long-term dependencies.
