Answer correct: 5
Reason: In the given figure series, the shaded region inside the inner triangle increases by one half-triangular part in each successive figure. Figures A, B, C, D, and E contain 1, 2, 3, 4, and 5 shaded half-parts respectively. Therefore, the next figure should contain 6 shaded half-triangular parts. Option 5 correctly follows this pattern. Moreover, the outer arrow-like symbol also changes position systematically in every step, which further supports Option 5 as the correct answer.
