Which one is it i’m so confused

How do you type these long ridiculous nguestion. oh, you copy n pasted. i see you. and that answer to the question is gonna be a quess from me. answer=c

  i think you forgot to put the options but if your reffering to this question then your answer will be "b"  a. add "to" to the base form to create an adjective.b. when the subject of a sentence is singular, add "–s" to the base form.c. add "–ed" to irregular base forms to form the past participle.d. do not use a base form with plural subjects
