In what year was introduced the original PC, used an 16-bit processor, but it only had an 8-bit bus to carry the data.
A
1981
B
1971
C
1961
D
1941
Explanation: 

Detailed explanation-1: -It was an 8-bit bus based on the I/O bus of the IBM System/23 Datamaster system-it used the same physical connector, and a similar signal protocol and pinout. A 16-bit version, the IBM AT bus, was introduced with the release of the IBM PC/AT in 1984.

Detailed explanation-2: -In late 1974, National introduced the first 16-bit single-chip microprocessor, the National Semiconductor PACE, which was later followed by an NMOS version, the INS8900.

Detailed explanation-3: -Motorola 68000 (1980) When Motorola released the 68000 in 1980, it was one of the most powerful chips on the market.

Detailed explanation-4: -A 16-bit ISA refers to a computer architecture in which the data bus and the memory address bus are both 16 bits wide. This means that the computer can access up to 64 kilobytes of memory at a time and can process data that is 16 bits wide.
