Final answer:
The correct statement reflecting a Musketeer attitude towards teamwork in a daily scrum is 'Our team needs to work together to overcome challenges.'
Step-by-step explanation:
The statement that a developer would use in a daily scrum team to demonstrate a Musketeer attitude is "b) Our team needs to work together to overcome challenges." This attitude reflects the well-known Musketeer slogan "All for one, and one for all," emphasizing teamwork and collaboration, which are fundamental principles of Agile and Scrum methodologies. This approach contrasts with individualistic statements that suggest working alone or in isolation, which do not foster the collective effort and mutual support encouraged in Scrum teams.
