In the following question, some parts of the sentence have been highlighted. You need to identify which of the given option can both grammatically and contextually replace the highlighted part. In case the highlighted part is correct, mark option E as your answer. At time his on-court demeanour and his grinding style of tennis have detracted from the perception of his success.

(d) Option a) is incorrect, since, 'in times' alone here does not add any meaning to the sentence. In option b), a noun is missing, which is to be qualified by the adjective 'on-court'. In option c) the phrase 'His on- court demeanor at times,' is not correct since, here 'at times' has been used for both 'his on-court demeanor' and 'his grinding style, not just for 'his on-court demeanor'. Hence, the correction option is d) 'At times, his on- court demeanor'. The highlighted part- 'At times' would be correct as the phrase gives the intended meaning of 'sometimes'.
