Step-by-step explanation:
The item that best completes the flowchart outlining the procedure for enacting laws in the legislative branch of government is D. Committee review and markup process.
When a bill is introduced, it is sent to the appropriate committee or subcommittee. The committee then requests written comments from relevant executive agencies, holds hearings to gather additional information and views, and works to perfect the measure by amending the bill or resolution. Once the language of the measure is agreed upon, the committee sends it back to the full legislative body for further consideration.
Therefore, the committee review and markup process is a crucial step in the legislative branch's procedure for enacting laws.
