Ruby - Enumerable and Collection Processing

Given two arrays products = ["Pen", "Notebook", "Eraser"] and prices = [1.5, 2.0, 0.5], which Ruby code correctly creates a hash mapping each product to its price using zip?

Aproducts.zip(prices).to_a

BHash[products.zip(prices)]

Cproducts + prices.to_h

Dproducts.zip(prices).flatten.to_h

Step-by-Step Solution

Solution:

Step 1: Use zip to pair arrays
products.zip(prices) creates array of pairs.
Step 2: Convert pairs to hash
Use Hash[] to convert pairs into a hash.
Final Answer:
Hash[products.zip(prices)] -> Option B
Quick Check:
Check for hash creation from zipped pairs [OK]

Quick Trick: Use Hash[] with zipped arrays to create hash [OK]

Common Mistakes:

Using to_a instead of Hash conversion
Trying to add arrays directly
Flattening before to_h causing errors
