Communications over relatively short distances can be made by visual or sound signals.Visual signals can be sent by using flags or an Aldis lamp.An Aldis lamp is an electric lamp used for flashing messages in Morse code.The traditional method of signaling from one ship to another is by using flags.There are different colored flags for each letter of the alphabet.There are also pennant-shaped flags for numbers，and a long pennant，known as an answering or code pennant.Three other flags，which are burgee-shaped，are known as substitutes.These show that the flat or pennant is being repeated.Besides standing for a letter of the alphabet，each flag，when hoisted along，has another meaning.For example，the “W” flag also means: “I require medical assistance”.Flags can also be hoisted in combinations of two，three or four.Siren，whistle，bell or other sound signals can be used in fog and similar circumstances when visual signals can not be seen.[93]Communications over relatively short distances may be made by ________.通信相关的距离相当短，可以不是视觉就是声号。
A.visual signals B.sound signals C.Morse Code D.Either visual or sound signals
