Correct answer
In those conditions, except when it may dazzle other road users.
Use main beam in these conditions, replacing it with dipped beam as soon as it may dazzle any road user, including drivers ahead through mirrors. Main beam does not guarantee optimal visibility in every circumstance; also adapt speed to the visible distance and conditions. Do not keep main beam on if it may dazzle.
