Correct Option: D
Explanation:

To solve this question, the user needs to carefully read and analyze the given statements to determine the correct option.

(i) A, B, C, D, E, F and G are seven members standing in a row (not necessarily in the same order) facing north.

(ii) C and B have as many members between them as G and C have between them.

(iii) D, who is 3rd from the extreme left, is 3rd to the left of E.

(iv) A and D are neighbors and F and C are neighbors.

Statement (ii) implies that C is at the center of the row. Statement (iii) implies that E is at the rightmost end of the row. So, the seating arrangement is as follows:

__ __ __ D A __ C F G E
1  2  3  4 5  6 7 8 9

Using the above arrangement, we can evaluate the given options.

A. C and E are neighbors - This option is incorrect because C and E are not neighbors. G is between them.

B. E is to the immediate left of F - This option is incorrect because E is not to the immediate left of F. C is between them.

C. C is to the immediate left of D - This option is incorrect because C is not to the immediate left of D. A is between them.

D. A is to the immediate left of D - This option is correct. According to the given arrangement, A is to the immediate left of D.

Therefore, The Answer is: D. A is to the immediate left of D.

Condition: (i) A, B, C, D, E, F and G are seven members standing in a row (not necessarily in the same order) facing north. (ii) C and B have as many members between them as G and C have between them. (iii) D, who is 3rd from the extreme left, is 3rd to the left of E. (iv) A and D are neighbors and F and C are neighbors.
