The first hand-held radios were introduced in 1960.

• A. 1940
• B. 1970
• C. 1960
• D. 1950

Answer: (C)

The main idea here is when portable two-way radios became practical for everyday field use. By 1960, advances in transistor technology and compact batteries allowed a person to carry a workable handheld radio, making portable communications feasible for regular operations. That shift—from bulky, non-portable gear to compact hand-held units—defines the era the question is pointing to. Earlier decades had only large or prototype devices, and later decades simply reflect an established technology. So, 1960 is the best answer because it marks the point at which handheld radios became truly practical and widely introduced.
