If there is a difference between early start date and late start date that means the activity has a FLOAT and is not on critical path.

 

1 def not on Critical path else there would be float of 0 or negative not +10 days

2 Def does not have a lag. Lag is the relationship between 2 activities and the relationship between sucessor or predecessor is not exaplained here

3 can be rules out since we don't know if its progressing well

Answer is D. The Q has a typo. Most probably the Q should should read 9 & 19 as the late dates. But late dates are not required to answer the Q.You can read more about it in the following article - 19 Frequently Asked Questions on the Critical Path Method
