$1.$a In the circuit below, how many transistors are needed with the current logic gates arrangement?

b$.$How many are needed if you implement the circuit with just NANDs? $($Use mixed logic$)$

c$.$ How many are needed if you implement th& circuit with just NORs? $($Use mixed logic$)$

d$.$ How many are needed if you do a custom CMOS transistor circuit for this Boolean expression? $($Without needing inverters, for example, you have accessto NOT A without an inverter$)$

e$.$ How many are needed if you do a custom CMOS transistor circuit and you need to make inverters for the complements of inputs?
