What was common among land bank and industry measures in Bolshevik economic policy?

Correct answer: Reducing old private control and increasing state or social control

The direct answer is A: reducing old private control and increasing state or social control. The common idea in Bolshevik economic measures was to challenge the ownership power of landlords, private capitalists and other old ruling groups. Reasoning: land policy weakened private landlord control and made land serve the wider peasant or social interest; banking and major industries were brought under public or state direction; therefore the shared direction was a movement away from the old private system. A is correct because it identifies this common direction without claiming that every sector was managed in exactly the same way. B is wrong because the Tsar was removed and did not receive all property. C is wrong because production was not handed to the Church. D is wrong because the aim was not to invite foreign owners to restore private control. The exam cue is to look for the ownership pattern, not superficial differences between policies.
