那一句子才對

usually, we put the time frame before the verb

therefore, the only correct answer will be B
We often go fishing

C is wrong because WE is plural, which means there should not be s/es behind the verb

fishing in this case act as a noun (the activity) rather than a verb.
go is the verb

第二句係啱嘅
We often go fishing啱嘅

第2個係對的!
"We"係多過一個人，所以之後既verb(動詞)一定唔會有"s"架! 所以"goes"係錯。

全部都錯！！答案應該係We go fishing often
希望幫到你。

We often go fishing 是對的，你可以說成 We go fishing often 亦可。
至於 We goes fishing本身就已經不對，he / she / it 才會用goes。

應該We often go fishing
因為Verb to be
often一定在人後面
we系眾數，5應該用goes

We go often fishing 我們去經常釣魚 We often go fishing 我們經常問釣魚 We often goes fishing 我們經常去釣魚
所以第三個先對(We often goes fishing 我們經常去釣魚)

We often go fishing

We often goes fishing(no we係第二人稱 係use are)

We go often fishing錯
We often go fishing對
We often goes fishing錯
