Best answer

Answer: 3. Spindle fibres attach to centromere of chromosomes.

Key idea: Spindle fibres attach to the kinetochores, which are protein discs on the centromere, rather than to the centromere itself.

Option 1: the centromere splits at anaphase, true.
Option 2: all chromosomes line up at the equator in metaphase, true.
Option 3: the fibres attach at kinetochores, so saying they attach to the centromere is the loosely worded, incorrect statement according to the official key.
Option 4: chromosomes decondense at telophase, true.
