Answer:
The property of equality that justifies this statement: if l=m , then m=l is:
b. symmetric property
Step-by-step explanation:
We know that the symmetric property of relations states that if a is related to b by any relation R i.e. a R b
then b is also related to a by the same relation i.e. b R a
Hence, we have a relation as a equality relation,
i.e. a R b means a=b
Hence, symmetric property states that
b R a that means b=a
Hence, the answer is:
Option: b
