The correct answer is A. Russia and Britain sent troops to protect their interest there
Explanation:
In the beginning of the twentieth century around 1908 it was found there was a large oil field in Persia which is now known as modern Iran. Knowing the economic advantage this field represented companies from Great Britain became immediately interested in this new discovery, because of this, companies of both countries negotiated a concession with the king of Persia to extract the oil. This was the case of the British company Anglo-Persian Oil Company which take advantage of the situation and was the first company in extracting oil from the zone.
In the case of Russia, during this historical period, the Russian Empire was the one that ruled Persia and therefore was equally interested in extracting the oil. This situation began a struggle between Russian and Britan that sent their troops to try to protect the territory where the oil was and divided the Persian Empire into different zones. Thus, one of the immediate effects of the discovery of oil in Persia (Iran) was that "Russia and Britain sent troops to protect their interests there" considering Britan had a concession with the king of Persia and Russia had power over the zone.
