Which is the correct syntax to stub a method greet on an object user using RSpec?

Auser.stub(:greet).returns('Hello')

Bstub(user).greet('Hello')

Callow(user).to receive(:greet).and_return('Hello')

Dmock(user).greet = 'Hello'

Step-by-Step Solution

Solution:

Step 1: Recall RSpec stubbing syntax
RSpec uses allow(object).to receive(:method).and_return(value) to stub.
Step 2: Match syntax to options
Only allow(user).to receive(:greet).and_return('Hello') matches this correct syntax.
Final Answer:
allow(user).to receive(:greet).and_return('Hello') -> Option C
Quick Check:
RSpec stub syntax = allow...receive...and_return [OK]

Quick Trick: Use allow(obj).to receive(:method).and_return(value) [OK]
