The answer is current -- A
Yes it is, because lucid means characterized by clear perception.
Answer : The molar mass of hemoglobin is, 
Explanation : Given,
Molar mass of iron = 55.85 g/mol
0.349 % Fe by mass that means 0.349 grams of Fe present in 100 grams of hemoglobin.
or,

Now put all the given values in this formula, we get:


Thus, the molar mass of hemoglobin is,
