Which of the following is an important feature of the sum-of-products (SOP) form of expression?
All logic circuits are reduced to nothing more than simple AND and OR gates.
The delay times are greatly reduced over other forms.
No signal must pass through more than two gates, not including inverters.
The maximum number of gates that any signal must pass through is reduced by a factor of two.
Answer: Option

If expression is like this F = A'B + AB' + AB.

Then we require 3 gates (and, or, inverters), So I think option (B) should be correct because SOP form is used to simplify the expression, hence it reduces gates and hence delays in the circuits.

@Sam.

You are correct, ie two level of gates required.

I think, they mean two gate levels. By this, I mean to say, for each product term, one AND gate is required. And for sum, one OR gate shall be required. Thus, any signal will pass through two gates only.
