【单选题】Which of the following is correct for the circuit shown in Figure 4?
A.
Decimal 10 is being written into memory location 211.
B.
The number 5 is being written to the memory at address location 203.
C.
The chip has not been enabled, since the EN terminal is 0; therefore, nothing will be written to the chip and the output is tri-stated.
D.
The read/write line is LOW; therefore decimal 5 is being stored at memory location 211.
