दिलेल्या घनाकारांपैकी सोबतच्या चौरससंचाची घडी घालून मिळू न शकणारे दोन घनाकार दर्शविणारा पर्याय निवडा :

The correct answer is Option A ((b) and (c)).

Key Points:
• In cube folding rules, opposite faces cannot appear adjacent to each other on the 3D cube.
• By analyzing the unfolded net in Q.151, the quarter-circle dot shading patterns on corner edges determine which faces meet at a vertex.
• Figure (b) shows four quarter-dots meeting to form a full circle at a single vertex, which is impossible based on the net geometry.
• Figure (c) similarly places non-adjacent patterns adjacent to one another.
• Thus, cubes (b) and (c) cannot be formed.
• Option 1 is correct.
• Key Takeaway: In cube folding, opposite faces can never be adjacent, and corner pattern alignments must match the net.
