Given this code, how can you store multiple method objects from an object obj for methods :foo and :bar and call them later?

class Example
  def foo
    "foo called"
  end
  def bar
    "bar called"
  end
end

obj = Example.new

Amethods = [obj.method(:foo), obj.method(:bar)]; methods.each { |m| puts m.call }

Bmethods = obj.methods(:foo, :bar); methods.call

Cmethods = obj.method(:foo, :bar); methods.call

Dmethods = [obj.foo, obj.bar]; methods.call

Step-by-Step Solution

Solution:

Step 1: Obtain Method objects individually
Use obj.method(:foo) and obj.method(:bar) to get Method objects.
Step 2: Store in an array and call each
Store them in an array and iterate to call each method object.
Final Answer:
methods = [obj.method(:foo), obj.method(:bar)]; methods.each { |m| puts m.call } -> Option A
Quick Check:
Store multiple Method objects in array and call each [OK]

Quick Trick: Store Method objects in array, call each with .call [OK]
