The correct option is BDCA.

To arrange the given segments into a grammatically correct and coherent sentence, let us analyze each part and their logical connections:

Step 1: Identify the subject of the sentence
Segment B, "the core principles outlined in the diplomat's address", introduces the main noun phrase and serves as the subject of the sentence.

Step 2: Connect parenthetical or modifying information
Segment D, "including the proposal for shared resources", naturally follows segment B to specify additional detail about the principles mentioned in B.

Step 3: Add the main verb and predicate
Segment C, "became the primary basis of the Geneva", contains the verb "became" and connects to the noun phrase established in B and modified by D.

Step 4: Complete the sentence with the object noun phrase
Segment A, "treaty signed a week later", completes segment C by forming the full proper noun phrase "Geneva treaty signed a week later".

Full Coherent Sentence:
"The core principles outlined in the diplomat's address, including the proposal for shared resources, became the primary basis of the Geneva treaty signed a week later."

Therefore, the correct sequence of the segments is B - D - C - A (Option BDCA).
