The answer is admiramos
The rule for verbs is whoever you are referring to (in this case 'nosotros'), you need to change the ending of the word.
Nosotros - amos
Yo - o
Tu - as
El, Ella, Usted - A
Ellos, Ellas, Ustedes - An
(Examples: Nosotros bailAMOS (instead of bailar) or Yo hablO (instead of habla)
