单选题 The Planning Committee has decided in favor of redeveloping the city's western district and has issued a report that argues for the feasibility of such redevelopment.

A、 Did the feasibility report include information compiled by independent consultants rather than by members of the committee?
B、 Do the committee's decisions require the unanimous support of its members?
C、 Has Johnston served on other municipal committees that are not concerned with issues of planning and development?
D、 Does the committee issue reports at regular intervals or only when a question on development is decided?
E、 (E) Have other members of the committee served on the committee as long as Johnston has?
