To determine the greatest common divisor (GCD) of 36 and 60, it's helpful to first identify the prime factorization of each number.

For 36:

- 36 can be factored into \(2^2 \times 3^2\).

For 60:

- 60 can be factored into \(2^2 \times 3^1 \times 5^1\).

The GCD is found by taking the lowest power of all prime factors common to both numbers.

- The prime factor 2 appears as \(2^2\) in both factorizations, so we take \(2^2\).

- The prime factor 3 appears as \(3^2\) in 36 and \(3^1\) in 60, so we take \(3^1\).

- The prime factor 5 appears only in 60, so it is not included in the GCD.

Now, we multiply these together:

\[

GCD = 2^2 \times 3^1 = 4 \times 3 = 12.

\]

Thus, the GCD of 36 and 60 is 12, confirming that this option is accurate
