PLEASE RATE POSITIVE IF THOU LIKE MY ANSWER TO PROTECT MY EMPLOYMENT

i) Activity on arrow network

II)

PATH	PATH LENGTH
ABCDGJLM	4+3+2+1+10+3+3+1 =	27
ABEFJLM	4+3+2+8+3+3+1 =	24
ABIJLM	4+3+3+3+3+1 =	17
ABHKLM	4+3+2+2+3+1 =	15

The critical path is path with longest length . Hence critical path is ABCDGJLM

iii) Gantt chart

iv) resource allocation chart
