Step-by-step explanation:
In English, "washing" can be both a present participle and a gerund, depending on how it is used in a sentence.
As a present participle, "washing" functions as an adjective or as part of a progressive verb form. For example, in the sentence "She is washing the dishes," "washing" is a present participle that describes the ongoing action of washing the dishes.
As a gerund, "washing" functions as a noun. For example, in the sentence "I enjoy washing," "washing" is a gerund that serves as the object of the verb "enjoy."
Therefore, the answer is either (A) Present participle or (D) Gerund.
