Can someone please explain how they got the answer as d in this question? I don't understand. Please explain thoroughly and clearly.

Q3) Given: struct M { /* ... */ }; struct E : M { /* ... */ }; struct Z: M { /* ... */ }; struct Q : E, Z { /* ... */ }; write the letter answer labels below that correspond to the all of the possibly TRUE statements that describe the memory layout type Q. (Marks will be deducted for wrong selections.) (a) The memory layout of Q is this class ordering: M, M, Z, E, Q. (b) The memory layout of Q is this class ordering: M, M, E, Z, Q. (c) The memory layout of Q is this class ordering: M, E, M, Z, Q. (d) The memory layout of Q is this class ordering: M, Z, M, E, Q. (e) The memory layout of Q is this class ordering: Q, E, Z, M (f) The memory layout of Q is this class ordering: Q, Z, E, M (g) The memory layout of Q is this class ordering: E, Z, M, M, Q (h) The memory layout of Q is this class ordering: Z, E, M, M, Q (i) None or not all answers are listed above. (If chosen, you MUST write (1) followed by the correct sequence(s) with each sequence separated by a semi-colon.)
