It's Time to Digit-Spread!

Logic Level 3

A B × C A 0 B \begin{array}{ccccc} & & & A & B\\ \times & & & & C\\ \hline & & A & 0 & B\\ \hline \end{array} Each of the letters contains distinct single-digit integer. What must be true about the divisibility of A 0 B \overline{A0B} , where the center digit is the number 0 0 ?


Bonus: It is possible that A B × C D = A 00 B \overline{AB} \times \overline{CD} = \overline{A00B} . Can we multiply A B \overline{AB} by a number with more distinct digits to obtain the product of the form ( A × 1 0 n + B ) \left(A\times 10^n + B\right) , where n n is some positive integer?

It is divisible by 3. it is divisible by 6. None of the answers. It is divisible by 5. It is divisible by 15.
