Let`s analyze the given information and relationships to determine how E is related to F.

1. D, the salesman, is married to the lady teacher.

This means D and the lady teacher are a married couple.

2. The doctor is married to the lawyer.

This implies that the doctor and the lawyer are a married couple.

3. F, the accountant, is the son of B and brother of E.

This tells us that B is F`s parent and E is F`s sibling. It also means that B and E are not married to each other.

4. C, the lawyer, is the daughter-in-law of A.

This indicates that A is C`s mother-in-law.

5. A is the grandmother of F.

This implies that A is F`s grandmother.

Now, let`s analyze the relationships:

D (salesman) and the lady teacher are a married couple.

The doctor and the lawyer are a married couple.

This means that D (salesman) is not married to the doctor or the lawyer. The only remaining option is for D to be married to the lady teacher.

C (lawyer) is the daughter-in-law of A (grandmother).

Since C is the lawyer and the daughter-in-law of A, it means that C is married to A`s child. However, we don`t have any information about A`s child or their gender.

E (engineer) is the unmarried sibling of F (accountant).

From the given information, it is clear that E is F`s sibling, and E is unmarried.

Considering the above information, we can conclude that E is a sibling of F, but we cannot determine the gender of E based on the given information. Therefore, the relationship between E and F can be established as "sibling" (brother or sister). Thus, the correct answer is Option 4: Cannot be established.
