Assertion (A): For serviceability, IS 456 specifies that when all loads (including temperature, creep, shrinkage plus finishes and partitions) act, the maximum deflection = lesser of span/350 and 20 mm. Reason (R): IS 456 provides basic span/depth ratios that generally ensure deflection limits are satisfied.
Both A and R true, R correct explanation
Both A and R true, R not explanation
A true, R false
A false, R true
