|The answer is wrong.
As per IS 456-2000 Clause 26.3.3 [b (1)], horizontal distance between parallel main R/f bars must be smaller of the foll:
1. 3 times effective depth i.e. 3 x 15 cm = 45 cm.
2. 30 cm.
So, correct answer is [A] 30 cm.

|Thanks @Barish Raut.|
|Ma Sohail said: (Jun 6, 2017)|
|Yes, you are correct @Barish Raut.|
|Priyal P said: (Dec 30, 2017)|
|No, 45 is right answer. See question is should NOT BE MORE.|
|Arun Kumar said: (Apr 6, 2018)|
|30 cm is correct because we always take smaller value.|
|Ankit Raj said: (May 29, 2018)|
|45 is correct. I agree with the given answer.|
|Utsav said: (Jan 4, 2019)|
|45 is correct that's why they have mentioned the depth of the slab.|
|Er Nk said: (Feb 7, 2019)|
|Read the question properly.
Not more than.
|Prasad Mhatre said: (Mar 12, 2019)|
|Correct explanation @Barish.
Option A is the answer because if it is mentioned that it is a secondary r/f then the correct answer is 450 but here it is main r/f.
|Chandu said: (Jun 1, 2019)|
|I think 3d or 450 whichever small.
As per question, 3d=3*150=450mm.
From above smallest among both is 450mm.
So the answer is 45 cm.
