### C. prófase
Explicação
## Step 1: Understanding the stages of mitosis### Mitosis is divided into four stages: prophase, metaphase, anaphase, and telophase. Each stage has distinct events that characterize it.## Step 2: Identifying the events in each stage### - **Prophase**: The nuclear envelope (carioteca) disintegrates, chromosomes condense, and the mitotic spindle fibers form.### - **Metaphase**: Chromosomes align at the metaphase plate.### - **Anaphase**: Sister chromatids separate and move to opposite poles.### - **Telophase**: Nuclear envelopes reform around the separated chromosomes, which decondense.## Step 3: Matching the events to the correct stage### The question asks about the stage where the disintegration of the nuclear envelope, condensation of chromosomes, and formation of mitotic spindle fibers occur. These events are characteristic of **prophase**.
