The correct answer for this exercise is: c) Although flash mobs have been happening since 2003, lately, they have become a trend

Explanation:

To understand the reason why c) is the correct option we need to analyze all of them.

However, we need to know first that complex sentences have a formula composition: an independent clause and one or more dependent clause. In other words, we will spot a rule of existence and then one or more consequences of that value "rule".

In a b and d cases, the independent clause is wrong because there is not a right condition or association followed by a dependent clause. We need something special to identify that there is going to be a change of idea and effect of the rule. In all these cases we declare that there is a rule but we don't have a proper construction of the phrase. Therefore, the dependent clauses are not properly written. The only C) case writes the independent clause correctly with its initial conditioning statement.

good question. i'll be looking into that. (this is a joke sir)
