The correct option is "to be sure that the design matches the client's needs."
During the design phase of web development, it is crucial to have close communication with the client to ensure that the final product meets their needs and expectations. By working closely with the client, the development team can identify the client's requirements, preferences and goals for the website, including design aesthetic, functionality, and user experience.
Continual communication ensures that the client has a clear understanding of the development process and progress, and they can provide feedback on the design and functionality at key stages. This feedback can be used to make necessary adjustments and improvements to the design to meet the client's specifications.
Having close communication with the client not only ensures that the design matches their needs but also helps to foster a strong client-developer relationship, leading to a successful and satisfactory outcome.
