Question

before the age of smartphones and social media, morse code was the ultimate form of long - distance communication. invented in the early 1830s, morse code was a system of dots and dashes that represented letters. because morse code could be transmitted via telegraph, it quickly became essential for sending messages across continents and oceans. one remarkable moment in the history of morse code occurred during the titanic disaster in 1912. as the massive ship sank into the icy waters of the north atlantic, jack phillips, the telegrapher onboard, used morse code to send out distress signals to nearby ships. unfortunately, both the titanics officers and passengers used the same radio channel, meaning that many messages were lost in a jumble of voices. but harold cottam, the telegraph operator on the nearby ship carpathia, happened to be awake. after hearing phillipss distress signals, cottam relayed the message to his captain, who immediately turned the carpathia northward. the carpathia reached the titanic in less than four hours, and the crew was able to rescue more than 700 passengers from the titanic. which detail from the text best supports the claim that the use of morse code was important during emergency situations? choose 1 answer: a \before the age of smartphones and social media, morse code was the ultimate form of long - distance communication.\ b \invented in the early 1830s, morse code was a system of dots

Explanation:

The text details the Titanic disaster where Morse - code distress signals were sent and led to the rescue of over 700 passengers. This shows its importance in emergencies. Option A only mentions long - distance communication in general, and option B just gives information about its invention.

Answer:

No option C is provided in the question. But based on the above explanation, the relevant detail would be about the Titanic rescue using Morse code distress signals. Since no correct option is fully presented among A and B, if we assume there was a correct option related to the Titanic rescue part, that would be the answer. If we have to choose from A and B, neither fully supports the claim about emergency situations, but if forced, none of the presented options (A and B) are correct.
