Cuisine from the north of China is one of the most popular kinds of food in India. But this is not the…

The correct choice is: “Southern Chinese cuisine frequently incorporates obscure ingredients that are difficult to locate, while the ingredients necessary to prepare Northern Chinese cuisine are easily found in most Indian grocery stores.”

The puzzle is why one Chinese cuisine is loved in India and another from the same country is unpopular. The obscure-ingredients statement gives a concrete reason: Southern dishes are hard to cook in India because their ingredients are hard to find, while Northern dishes are easy to prepare. So one is widely available and the other is not.

The statement about immigrants from all parts of China suggests both cuisines arrived equally, which deepens the puzzle. The comparison with Italian food only repeats that Northern cuisine is popular. The statement that Northern cuisine takes more time and labour points the wrong way: it would make Northern cuisine less popular, not more.
