Q: What is the correct answer for NCERT11?

The correct answer is C. X-ray diffraction data reveals that all six C-C bond lengths in benzene are equal (139 pm), which is intermediate between a typical C-C single bond (154 pm) and a C=C double bond (133 pm). This indicates delocalization of electrons, not fixed alternating bonds.
