When a citation reference is an integral part of a sentence, such as:
Gordon and Metric provide a wide review of the key mechanisms...
Where and how is it best to place the citation reference (in APA style)?
A) Place the citation as part of the sentence:
(Gordon & Metric, 2012) provide a wide review...
B) Place the citation right next to the authors' names (the repetition seems a bit awkward to me):
Gordon and Metric (Gordon & Metric, 2012) provide a wide review...
C) Place the citation at the end of the sentence:
Gordon and Metric provide a wide review [...] of the financial crisis (Gordon & Metric, 2012).
