Question

why does victor choose the orkney islands in scotland as his workplace? (1 point)
they are isolated, with few people nearby to witness his experiments
he wants access to rare scientific materials there
elizabeth suggests it as a peaceful retreat
the creature forces him to go there

Explanation:

In Frankenstein, Victor chooses the Orkney Islands because they are isolated. This isolation means few people are around to witness his unorthodox and disturbing experiments (creating a female creature as per the Creature's demand). There's no mention of rare scientific materials being a draw. Elizabeth doesn't suggest it as a retreat in this context. And while the Creature demands a companion (which leads Victor to go to Orkney to create it), it's the isolation of the location (not being "forced" in a direct physical - like way) that is the key reason for choosing the Orkney Islands as a workplace for the experiment.

Answer:

They are isolated, with few people nearby to witness his experiments.
