Plz help don’t send link

Okay so i'm taking an online spanish course (penn foster), and in the study guide, you have to create a bunch of sentences with words you've learned so far. translating, reading, and those kinds of things are fairly easy, but when it comes to making my own sentences, my brain just kinda waltz's away. anyone got any tips?

Cuando en un relato se hacen descripciones físicas y psíquicas de un retrato se llama paisaje como a la de los lugares

Which verb form best completes this sentence? pablo picasso el estilo de cubismo. a. invente b. inventaste c. inventó d. invento
