Question

• A. ever
• B. since
• C. at
• D. for

Answer 1

Answer:

B. since

ഇവിടെ ഉപയോഗിക്കേണ്ട tense 'Present perfect continuous' ആണ്. കാരണം 'Present perfect continuous' ന്റെ time words ആണ് 'since' ഉം 'for' ഉം. Present perfect continuous ന്റെ format : subject + has/have + been + ing form + RPS( Remaining part of the sentence.) She + has ( Subject She വന്നാൽ has ആണ് auxiliary verb ഉപയോഗിക്കേണ്ടത്.) + been + waiting here+ since six O'clock.
