love _ (go) to see my grandparents!

I love going to see my grandparents!

Объяснение:

Эта фраза означает "Я люблю ходить (встречаться) с моими бабушкой и дедушкой".

Слово going (именно с таким окончанием) в контексте означает "хождение" (как процесс) :)

То есть вы любите хождение к бабушке и дедушке.
