I ......... unwell for more than a month.
Aam now
Bam still
Chave been
Dhave feeling
Answer:
C. have been
Read Explanation:
Have been is used in the present perfect tense to describe a state that began in the past and continues up to the present.
For more than a month indicates a duration of time.
Am now indicates the present state but does not naturally express the duration beginning in the past.
Am still indicates that the condition continues, but it does not fit the sentence as naturally as have been.
Have feeling is grammatically incorrect here. The correct expression would be have been feeling.
