Question

how is statement iv always true??

Comments

no even if a max weight edge is not in cycle it is to be included, consider graph::

AC = 100,DC = 101,CB = CE = BE = 1

So, (4) is definitely true. And According to me (3) is also true, but i mean to say maybe there exists a counter example for option (iii) statement.

alright..thanks @mcjoshi..:)
