The correct answer is Option 4 i.e. PQRS.
Follwing steps should be followed to solve the given question:
-
Identify the subject and predicate of the sentence. Here, the subject is "A 2007-2009 study" and the predicate is "explored forward thinking techniques to synchronise time on board deep space probes for accurate navigation, in particular looking into low-cost options."
-
Identify the different parts of the predicate, i.e., the different phrases that modify the main verb "explored." Here, we have four phrases: "forward thinking techniques," "to synchronise time on board deep space probes," "for accurate navigation," and "in particular looking into low-cost options."

Rearrange the phrases in a logical order. The sentence makes the most sense when the phrases are arranged in the following order: "to synchronise time on board deep space probes for accurate navigation, in particular looking into low-cost options, explored forward thinking techniques."
-
Combine the rearranged phrases with the subject to form the complete sentence.
Thus, the correct sentence will be:
A 2007-2009 study explored forward thinking techniques to synchronise time on board deep space probes for accurate navigation, in particular looking into low-cost options.
