For the remaining questions, consider the following problem description: An oil company is considering exploring new well sites S₁, S2, ..., S10 with respective costs C1, C2, C10. And in particular they want to find the least-cost selection of 5 out of the 10 possible *** 3 sites. The binary decision variables X₁, X2,..., X10 denote the decision to explore the corresponding site.

Provide the best interpretation of the constraint: x₂ ≤X6 + X9
O
O
Exploring site S₂ is possible only if sites S, and S, are explored
Exploring site S₂ prevents exploration of the combination of sites S6 and S9
Exploring site S₂2 is impossible unless at least one of S6 and S, are explored
Exploring site S, and S, requires exploration of site S₂
