It's not A because both countries have a republican system of government.
It's B, Lebannon is a confessional state and different religious groups have their specific place in the government, for instance, the president must be a Maronite Christian, the prime minister a Sunni Muslim, the speaker of the parliament a Shi’a Muslim, the Deputy Prime Minister and the Deputy Speaker of Parliament Eastern Orthodox. On the flip side, although Israel is a Jewish state it is in practice secular, so no religious or irreligious group has any special status in the country.
It's not C because Jews make up for less than 1% of the population in Lebannon and they do not have any special status in the politics of the country. As stated before, Israel has no policies regarding religious groups sharing power in the country.
It's not D because Hamas has some political dominance over the Gaza strip basically.
