Consider the following 4-variable Boolean function

$$ F(A, B, C, D)=\Sigma m(0,1,2,3,8,9,10,11) $$

Consider $A$ as MSB, $D$ as LSB. Which one of the following options represents the minimal sum of products form for the above function?

Note: + is OR operation, • is AND operation, ' is NOT operation

Consider a Boolean function $F$ with the following minterm expression:

$$ F(P, Q, R, S)=\Sigma m(1,2,3,4,5,7,10,12,13,14) $$

Which of the following options is/are the minimal sum-of-products expression(s) of $F$ ?

Given the Following Karnaugh Map for a Boolean function $F(w,x,y,z)$:

Which one or more of the following Boolean expression(s) represent(s) F?

Consider the following four variable Boolean function in sum-of-product form

$$F\left(b_3, b_2, b_1, b_0\right)=\Sigma(0,2,4,8,10,11,12)$$

where the value of the function is computed by considering $b_3 b_2 b_1 b_0$ as a 4-bit binary number, where $b_3$ denotes the most significant bit and $b_0$ denotes the least significant bit. Note that there are no don't care terms. Which ONE of the following options is the CORRECT minimized Boolean expression for $F$ ?
