Words A with E and B with D are to be interchanged as mentioned. In the place of word A, a 'to-be' verb is required and in the place of word E, a verb in base form (V1) is required. Accordingly, word A 'reach' is a verb in the base form (V1) and word E, 'was' is a 'to-be' verb that can take each other's place. Similarly, in the place of word B, a preposition is required and in the place of word D, an adjective is required to qualify the noun 'places'. Accordingly, word B, 'beautiful' is an adjective and word D, 'of' is a preposition and thus they interchange their positions, respectively.
The correct sentence is: It was one of the most difficult, most beautiful places to reach anywhere in Norway.
Hence, the correct answer is option (b).
Note:
Linking verb: A verb that connects the qualities of an object or person to that object or person. Example: The girl we met at the conference was intelligent and beautiful. Here, 'was' is the linking verb. It connects the qualities (intelligent and beautiful) with the person (girl).'

I. The teacher scolded the child for being late.
