To address question (b) for part (i), (ii), and (iii), I'll need to analyze the graph structure provided in the image. I will extract the necessary information and solve each part systematically. Let me process this image first. PIL import Image import pytesseract

Load the uploaded image

image_path = '/mnt/data/1733301478541hpi6zly0.jpg' image = Image.open(image_path)

Extract text from the image

extracted_text = pytesseract.image_to_string(image) extracted_textThe extracted text outlines the problem description but doesn't capture the diagram, which is essential for solving the problem. To proceed, I will need to recreate or interpret the graph structure (nodes and edges with weights) based on your input. Please provide details of the graph's structure (e.g., node connections and their respective weights) so I can compute the solutions.
