B,D Correct answer
Explanation

Option A is valid 1D array initialization. Option B has two errors: missing inner braces for 2D structure, and incorrect syntax - should be {{2,7,6}, {9,3,45}}. Option C is valid String array. Option D is invalid - cannot specify size [3] when using array initialization syntax; either use new boolean[3] or the initialization syntax, not both.
