Step 1: Pulses production over years
2011 = 150, 2012 = 50, 2013 = 200, 2014 = 150, 2015 = 250, 2016 = 350.
Total Pulses = \( 1150 \).
Step 2: Wheat production over years
2011 = 250, 2012 = 150, 2013 = 400, 2014 = 100, 2015 = 150, 2016 = 300.
Total Wheat = \( 1350 \).
Step 3: Ratio
Pulses : Wheat = \( 1150 : 1350 = 115 : 135 = 23 : 27 \).
\[
\boxed{23 : 27}
\]
So the correct option is (d), not (b).
