Show answer and explanation
Correct answer: (B) Diagram B
Explanation
A six-transistor SRAM cell requires two cross-coupled CMOS inverters and two NMOS access devices controlled by the word line, connecting complementary storage nodes to BL and BL̄. **B** has these devices and cross-coupled connections. A lacks the necessary cross-coupling, while C and D use incorrect transistor types in the inverter or access positions.
