Choose the similar pair to the given pair.
Given pair: $11:1210$

Let's investigate the relation in the pair $11:1210$:
Notice that $11^3=1331$ and $11^2=121$.
If we subtract the square from the cube: $1331-121=1210$.
Alternatively, the pattern can be expressed as: $n^2(n-1)$.
Let's check for $n=11$: $11^2\times (11-1)=121\times 10=1210$.

Let's test this pattern $n^2(n-1)$ on the options:

* Option A: $6:216⟹6^2\times 5=36\times 5=180\ne 216$.
* Option B: $7:1029⟹7^2\times 6=49\times 6=294\ne 1029$.
* Option C: $8:448⟹8^2\times (8-1)=64\times 7=448$. (Matches perfectly!)

Thus, the pair $8:448$ follows the same logic.
