It seems to me the equation is: B + (A & C') + (A' & C)

I don't have a decent way to draw the schematic so I'll write equations with temp outputs

Nand(A & A) -> temp1 - create A' - invert the 3 inputs
Nand(B & B) -> temp2 - create B'
Nand(C & C) -> temp3 - create C'

Nand(A & temp3) -> temp4
Nand(C & temp1) -> temp5
Nand(temp2 & temp4 & temp5) - create output D

3 inverters, 2 2-input NAND gates and 1 3-input NAND gate.

I think that's right...

See attached.  You need to verify the Truth Table.
