In the following question one or more parts of the sentence contain an error.Find out that part and mark the remaining i.e the errorless combination as the answer.
Oppo is mainly known at targeting (A)/ China’s young consumers with its trendy designs (B)/ and smart marketing and thus in 2016, the brand (C)/ was ranked being the number 4 smartphone brand globally.(D)
The error in A is the preposition 'at' and should be replaced with 'for' as something is known 'for' a characteristic.
The error in D is the word 'being' which needs to be replaced with 'as'. 'Ranked as' means 'categorized as.'
Thus option 1 is the correct answer.
