A

Input data → Generate hidden state → Output prediction

B

Generate hidden state → Input data → Output prediction

C

Output prediction → Input data → Generate hidden state

D

Input data → Output prediction → Generate hidden state

Understanding the Answer

Let's break down why this is correct

Answer

When an RNN processes a sequence, it first receives the first input element and combines it with an initial hidden state, usually set to zero. It then updates the hidden state by applying a nonlinear transformation that mixes the current input with the previous hidden state, producing a new hidden state that carries information from all past inputs. This updated hidden state is used to generate an output for that time step, often through a separate linear layer. The process repeats for each subsequent input, creating a chain of hidden states that encode the entire sequence. During training, the network learns by back‑propagating errors through this chain (back‑propagation through time), adjusting weights so that the hidden states capture useful patterns, such as predicting the next word in a sentence.

Detailed Explanation

An RNN reads the sequence one piece at a time. Other options are incorrect because It sounds like the RNN could know something before seeing any data, but it cannot; The prediction cannot come before any data.
