Question

Which possible combination of aquifers are encountered by deep wells depending on the hydro-geological characteristics of a particular area:
(A) A series of confined aquifers
(B) A series of semi confined aquifers
(C) A combination of confined and semi confined aquifers
(D) A confined aquifer underlain by a series of unconfined aquifers
(E) An unconfined aquifer underlain by a series of semi-confined aquifers
Choose the correct answer from the options given below:

• A. (A), (B), (C) and (E) only.
• B. (A), (B), (D) and (E) only.
• C. (A), (C), (D) and (E) only.
• D. (B), (C), (D) and (E) only.

Hint:

To eliminate options quickly:
A confined aquifer cannot sit directly above an unconfined aquifer.
Excluding (D) from the options immediately leads to the correct answer.

Answer 1

The Correct Option is A
