Just to elaborate on the cause-effect relationship that Ashish has mentioned about option C:
The 2 events - the USD defying policymakers' efforts to restrain it, the USD reaching the highest level in 6 years against the German mark - are not disconnected. The second is an outcome of the first.
'And' is a conjunction typically used to talk about 2 different ideas. Here, the ideas are not separate. Therefore, the use of 'and' is not appropriate here. This is the problem with option C, apart from the idiomatic issue.
