The correct answer is A. 1 to 11 gates.
SSI stands for Small Scale Integration. It is a technology used to integrate a small number of electronic components, typically from one to ten, onto a single integrated circuit (IC). SSI devices are typically used in simple circuits, such as logic gates and flip-flops.
B. 12 to 99 gates is the functional capacity of MSI devices, which stands for Medium Scale Integration. MSI devices are typically used in more complex circuits, such as counters and registers.
C. 100 to 10,000 gates is the functional capacity of LSI devices, which stands for Large Scale Integration. LSI devices are typically used in very complex circuits, such as microprocessors and memory chips.
D. more than 10,000 gates is the functional capacity of VLSI devices, which stands for Very Large Scale Integration. VLSI devices are typically used in the most complex circuits, such as graphics processors and supercomputers.
E. None of the above is not a valid answer.
