Deactivate form rasa 2.x

I have a rule which is having multiple forms like below.

  • rule: Delete webex account steps:
    • intent: sample_intent
    • action: action_a
    • action: action_b
    • action: action_form_c
    • active_loop: action_form_c
    • active_loop: null
    • action: action_form_d
    • active_loop: action_form_d
    • active_loop: null
    • action: action_form_e
    • active_loop: action_form_e
    • active_loop: null

Whenever action_form_c is active user can enter cancel instead of providing proper input value and at that time I don’t want to execute other actions below that form and want to run some other actions. How can I achieve that?
