I think not, a) is written to two digits before the decimal, sci notation has one digit.
Letter A) is not in scientific notation do to the fact that 51. what ever is higher than ten, and to be a valid notation the first number has to be between one and ten, no lower then one and no higher than ten, so letter A) would not be in scientific notation
