Purpose of a multi-stage build

What is the main benefit of this Dockerfile pattern?

FROM python:3.12 AS build
COPY requirements.txt .
RUN pip wheel --wheel-dir /wheels -r requirements.txt

FROM python:3.12-slim
COPY --from=build /wheels /wheels
RUN pip install --no-index /wheels/*
COPY app/ /app

A.The final image has no compilers or build caches, so it is smaller and has less attack surfaceB.It makes the model more accurateC.It lets the container use a GPUD.It removes the need for a requirements file
