In this case, it's 説明 (explanation). ⚫︎ The particle の (no) connects 鈴木さん (Mr. Suzuki) and 説明 (explanation), showing possession or belonging (Mr. Suzuki's explanation).

⚫︎ わかりやすい (wakariyasui) is an "i-adjective" (also known as a type 1 adjective). ⚫︎ "I-adjectives" end in い (i). ⚫︎ In this sentence, わかりやすい is in its polite form わかりやすいです (wakariyasui desu). ⚫︎ To make it negative, you change the い (i) to く (ku) and add ない (nai): わかりやすくないです (wakariyaku nai desu) - It is not easy to understand. ⚫︎ To make it past tense, change the い (i) to かった (katta): わかりやすかったです (wakariyasukatta desu) - It was easy to understand. ⚫︎ To make it past negative, change the い (i) to く (ku) and add なかった (nakatta): わかりやすくなかったです (wakariyaku nakatta desu) - It was not easy to understand.

⚫︎ While わかりやすい is an "i-adjective", the sentence utilizes the "desu" form to show politeness. ⚫︎ The verb です (desu) is a polite copula (a linking verb, like "is" or "are"). ⚫︎ It's added to the end of an adjective or a noun to make the sentence polite.

⚫︎ The particle の (no) in 鈴木さんの (Suzuki-san no) indicates possession or belonging. ⚫︎ It connects a noun to another noun, showing that the second noun belongs to or is related to the first. ⚫︎ In this case, 説明 (explanation) belongs to 鈴木さん (Mr. Suzuki).

⚫︎ The particle は (wa) functions as the topic marker. ⚫︎ It indicates the main topic of the sentence. ⚫︎ It often follows the subject or the thing that the sentence is about. ⚫︎ In the sentence, the topic is 説明 (explanation).
