Answer:
Él está duchando.
Step-by-step explanation:
Él is the pronoun for "he." The present progressive tense is what we think of as "-ing" in English. In Spanish, it takes the form of "estar + -ando/-iendo." To conjugate the verb estar in this sentence, you use the "èl/ella/usted" -ar form, which is -a, and add an accent. The verb "duchar" means to take a shower, and since it is an -ar verb, you use the ending -ando to create duchando.
