The salinity of seawater is commonly expressed as the amount of dissolved salts in grams per kilogram of seawater. On average, seawater contains about 35 grams of dissolved salts per kilogram, not 1 gram. Sodium chloride (common salt) makes up about 85% of these dissolved salts, so roughly 30 grams of sodium chloride are present per kilogram of seawater. Therefore, the correct amount of common salt in 1 kilogram of seawater is approximately 30 grams, which is not among the options A (1 gram), B (10 grams), or C (1 kg). Hence, the correct answer is D (None of these).

According to the Big Bang Theory, the Universe began about 13.8 billion years ago, which does not fall within any of the ranges provided in options A, B, or C. Therefore, the correct answer is 'None of these'.
