Problem Statement:

You are working on a customer referral management system that tracks customer referrals for new leads. You are given two custom Salesforce objects: Customer__c and Lead__c. The Customer__c object has the following fields:

• Id: A unique identifier for the customer
• Name: The name of the customer
• Email__c: The email address of the customer

The Lead__c object has the following fields:

• Id: A unique identifier for the lead
• Name__c: The name of the lead
• Email__c: The email address of the lead
• Status__c: A picklist field with values 'Open', 'Closed', and 'Converted'

Write a Salesforce Apex method that takes in a Lead__c object as input and returns a list of customers who have referred the lead. A referral is considered valid if the referred customer's email address matches the email address of the lead.

Input:

• A Lead__c object

Output:

• A list of Customer__c objects who have made valid referrals for the given Lead__c object

Example Input:

Lead__c(Id='XYZ123', Name__c='John Smith', Email__c='[email protected]', Status__c='Open')

Example Output:

[
   Customer__c(Id='C001', Name='Jane Doe', Email__c='[email protected]'),
   Customer__c(Id='C002', Name='Bob Johnson', Email__c='[email protected]')
