The following question has a paragraph from which the last sentence has been deleted. From the given options, choose the one that completes the paragraph in the most appropriate way.

Research on animals is performed to gain more knowledge about diseases and how to cure them, and to evaluate drugs for toxicity before testing them on humans. In fact, animal studies have played a vital role in almost every major medical advance.Gaining useful knowledge from animal research requires robust experimental findings: different scientists should be able to reproduce them in different locations. _________________
OPTIONS
 
 This requires a thorough understanding of each animal species and its biology.
 However, evidence is gradually accumulating that the majority of research animals are mentally stressed by their living conditions.
 Between 50 and 100 million animals, from flies to monkeys, are euthanized for research each year worldwide.
 Many scientists, however, are unaware that their animal facilities can affect research outcomes and compromise their data.
 However, rigorous standardization of the environment increases the risk of obtaining results that, being specific to a narrow set of conditions, cannot be compared with other researchers’ results.

In the kingdom of Einsteinia, a landlord died of a conspicuous disease leaving behind a property of 1000 gold coins. He was survived by 6 sons. In the kingdom, there was a rule that after the death of the elderly, the money is distributed to the descendents by the following rule.

The eldest of the siblings proposes a plan to distribute the coins among them. All of them vote in favor of or against the plan. If the proposer gets more than 50% support (including his vote) his plan gets accepted and the coins are distributed according to the plan. Otherwise, he does not get any coin. The voting process is then followed with the remaining five and the next eldest one proposes a plan and so on. If the process continues till the youngest sibling is left, he would walk away with all the coins.

The siblings are not expected to collude and have some different plan as there is a danger that if discovered they might be debarred from claiming a stake in the property and might face some stringent punishment.

Whose plan would get approved and what would be the distribution of coins. Provide a detailed explanation for the answer.
