विविध रंगाच्या, समान आकाराच्या, सहा चौरसाकृतींमध्ये विभागलेले कागदाचे चार तुकडे दिलेले आहेत. त्यांची घडी घालून घनाकृती तयार करता येते. ज्या तुकड्यांपासून बनविलेल्या घनाकृतीच्या समोरासमोरील बाजूंवर निळा आणि पांढरा रंग येईल, असे कागदाचे तुकडे निवडा.

The correct answer is Option B (One and four both).

Key Points:
• In the net of a cube, faces that are opposite to each other are separated by exactly one square in a straight row or column:
• In Net (1): 'White' is at the top tab (above Green), and 'Blue' is at the bottom tab (below Yellow). When folded, the top flap and bottom flap fold towards each other to form opposite vertical faces (White opposite Blue). This works!
• In Net (2): 'Blue' is in the top-left row, but opposite faces in this geometry pair Blue with Orange/Red, not White.
• In Net (3): 'Blue' is in the row adjacent to 'White' (Blue - White - Yellow), meaning Blue is opposite Yellow, NOT White.
• In Net (4): In the row/column structure, 'Blue' folds to be opposite to 'White' due to the staggered step layout.
• Thus, nets (1) and (4) both yield cubes where Blue and White are on opposite faces. Therefore, Option 2 ('One and four both') is the correct answer.
• Key Takeaway: In cube nets 1 and 4, the relative positioning ensures that the Blue and White colored faces fold into opposite sides.
