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 sites. The binary decision variables X₁, X2,..., X10 denote the decision to explore the corresponding site. *** 3

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
sites. The binary decision variables x₁,x2,..., X10 denote the decision to explore the corresponding
site.

Provide the best interpretation of the constraint:
O
X3 + X5 ≤ 1
X₁ + X5 ≤ 1
Exploring site S3 or site S4 prevents you from exploring site S5
O
Exploring site S3 requires exploration of S4 or S5
Exploring sites S3, S4, and S5 is only possible if another constraint is disjunctive
Exploring the combination of sites S3 and S4 prevents you from exploring S
