The Correct Option is D

Solution and Explanation

Concept:
The seismic zone factor \(Z\) represents the expected peak ground acceleration for the maximum considered earthquake in a region. As per IS 1893, India is divided into four seismic zones II, III, IV and V with zone factors 0.10, 0.16, 0.24 and 0.36 respectively.

Step 1:
Hyderabad lies in Seismic Zone II, which is the zone of lowest seismic hazard in the country.

Step 2:
The zone factor assigned to Zone II is \(Z = 0.10\).

Answer: Option (4) — 0.10.
