Question Analysis
This question tests the student's ability to factor a multivariable polynomial using the grouping method.

Key Concept Explanation
The grouping method involves dividing the polynomial into two groups, extracting the greatest common factor (GCF) from each group, and then factoring out the common binomial factor.

Step-by-step Solution
Step 1: Group the terms into two pairs
Group the first two terms and the last two terms:
Step 2: Factor out the GCF from each group
From the first group , the GCF is 7pq:
From the second group
