70% to pass

What would a signal indicating Greenwich mean time would be preceded with?

A the letter Z
B the letter G
C the letters GT
D a code hoist to indicate Greenwich mean time to follow
AI Explanation

The correct answer is A) the letter Z. The letter "Z" is used to indicate Greenwich Mean Time (GMT) or Coordinated Universal Time (UTC) in maritime and aviation communications. This is an internationally recognized standard practice, as GMT/UTC is the universal time reference used for navigation and coordination of operations globally. The other options are incorrect because: B) the letter "G" is not the standard prefix for GMT/UTC, C) the letters "GT" do not have a defined meaning in this context, and D) a code hoist is not typically used to indicate GMT/UTC - the standard practice is to use the letter "Z" as a prefix.
