The correct option is D
(d) 21

Number of students in Primary and High School combined = $3276 \times \frac{2}{3} = 2184$

Number of teachers in Primary and High School combined = 2184/26 = 84; (as the Teacher-Pupil ratio is 26 for both);

Given, the ratio of teachers in Primary to High School = 3:1;

Number of teachers in High School = $84 \times \frac{1}{4} = 21$
