The correct option is A The statue is too beautiful to be sculpted by an average sculptor.
The proper structure to construct a sentence using 'too' with an infinitive is:
too + adjective/adverb ... to + base form of the verb
In light of this concept, it can be seen that the sentence 'The statue is too beautiful to be sculpted by an average sculptor' follows the structure properly. The adverb 'too' needs to sit beside an adjective or an adverb to show the extent of its amount that is to appropriate the expression 'more than enough'. Hence, Option A is correct and the other options cancel out.
