• A determiner is "a word which is used at the beginning of a noun group to indicate, for example, which thing you are referring to or whether you are referring to one thing or several".
• We use the determiner 'whose daughter' as it perfectly defines the relationship between the teacher and my classmate.
• Option 1, 'her daughter' is incorrect as it does not join the sentence, but instead separates it, i,.e "my mother met the teacher. Her daughter is our classmate".
• Option 2, 'the daughter of us' is also an incorrect option as it doesn't grammatically makes sense when used in the sentence.
• Option 3, 'who is daughter' is itself a phrase with grammatical error and cannot be used to fill in the blanks.
• Hence the correct option is option 4.

• Preposition "on" is correct to fill in the second blank.
• "Hook on" means very interested and enthusiastic about something.
  • Example: She got hooked on the show after watching one episode.

Hence, the correct answer is option 2.

From Statement 1:

We have,

‘Be careful’ is coded as ‘oqa ahw’

In the same code language ‘dnj msk ahw swe’ means ‘May be next time’

Here, we can’t find the code for ‘Time’.

From Statement 2:

We have,

‘Be careful’ is coded as ‘oqa ahw’

In the same code language ‘vnm msk qqa oqa’ means ‘Careful you are next’

Here, we can’t find the code for ‘Time’.

From Statement1 and Statement2:

We have,

‘Be careful’ is coded as ‘oqa ahw’

In the same code language ‘dnj msk ahw swe’ means ‘May be next time’

In the same code language ‘vnm msk qqa oqa’ means ‘Careful you are next’

P is male member and married to Q.
P is husband and Q is wife.
R is brother of P.
S is the son of R.
T, who is the sister of S will be daughter of R.
Q is the daughter-in-law of U, whose husband has died means U is the mother of P.

Clearly, C is the grandchild of A.

Hence, ‘Grandchild’ is the correct answer.

Peel : Peal

The above words represent pair of homophones.

(c) is a pair of homophones. (a), (b) and (d) do not have pairs of homophones.

Hence according to meanings, Option A is correct.

From the common explanation, we get R sits exactly opposite to U.
Hence, Option C is correct.
Final Arrangement:

Common Explanation:
References:
Exactly two persons are sitting between P and Q.
Only one person is sitting between P and U.
Inferences:
From the above references, we get two different cases:

References:
S is sitting second to the right of R.
Inferences:
From the above reference, we get the following arrangements:

References:
T is not sitting beside S.
Inferences:
So, from this case 2 will be eliminated as T is not sitting beside S.
Hence, we get our final arrangement:
