In the context of provisions relating to durability of concrete, consider the following assertion: Assertion (1): As per IS 456-2000, air entrainment to the extent of 3% to 6% is required for concrete exposed to marine environment. Assertion (2): The equivalent alkali content (in terms of Na₂O equivalent) for a cement containing 1% and 0.6% of Na2O and K₂O, respectively, is approximately 1.4% (rounded to 1 decimal place). Which one of the following statements is correct? A. Assertion (1) is true and Assertion (2) is FALSE B. Both Assertion (1) and Assertion (2) are TRUE C. Both Assertion (1) and Assertion 2) are FALSE D. Assertion (1) is false and Assertion (2) is TRUE
