The most accurate response to why a cell must grow larger early in the cell cycle is:
The cell grows larger to allow ribosomes the space to build centrioles.
While all the given options may have some relevance in a broader context, this option directly addresses a specific need during the cell cycle in preparation for cell division.
The cell grows larger to ensure there are enough resources and space for all processes necessary for replication, such as the synthesis of DNA and the production of necessary cellular components, including centrioles that are required for proper cell division. The other options, while related to cell function and efficiency, do not specifically address the role of growth in the context of the cell cycle's progression leading to division.
