Solution
Let $$X$$ = $$3^{3^{333}}+1$$
=> $$X-1$$ = $$3^{3^{333}}$$
Let $$Y$$ = $$3^{3^{334}}+1$$
$$Y-1$$ = $$3^{3^{334}}$$
$$Y-1$$ = $$(3^{3^{333}})^{3}$$
=> $$(Y-1) = (X-1)^{3}$$
On expanding, The 1s on both sides will get cancelled. Y can be represented in terms of X. This clearly indicates that X is a factor of Y.
Therefore, the HCF is $$3^{3^{333}}+1$$
Option C is the right answer.
