If the row values in multiple columns = 1, set another column's row value to 1, else set to 0

I have a table in which multiple columns contain either 0s or 1s. Lets say the columns are called A, B, & C.

I need to add a column, D, which has a value of 1 if within that row, A, B & C all have values of 1. If not, then D should have a value of 0 for that row.

Ive attached a .mat file with columns A, B & C for an example, but I need the addiitonal column 'D' added to the table:

A       B      C      D

0	1	1	0
0	1	1	0
1	1	1	1
0	0	1	0
1	1	1	1
1	1	0	0
0	0	0	0
1	1	1	1
0	0	0	0
1	0	0	0

% I tried doing something like this but didnt work and seems inefficient:
for i = 1:height(X)
    if X(i,'A') == 1 && X(i,'B') == 1 && X(i,'C') == 1 
        D = [D 1];
    end
end

D=all(   X{:,{'A','B','C'}} , 2);

X=[X,array2table(D)]

I have other columns in the table that need to remain the same, so this isn't working for me. I uploaded a sample table as a .mat file with columns A, B, & C which are needed to create column D
