To answer this question, we first need to understand the units of radioactivity: microcurie, rutherford, and becquerel.

1. Microcurie (μCi): This is a unit of radioactivity equal to one millionth (10^-6) of a curie, or 3.7 x 10^4 disintegrations per second.

2. Rutherford (Rd): This is a unit of radioactivity, defined as the activity of a quantity of radioactive material in which one million (10^6) disintegrations occur per second.

3. Becquerel (Bq): This is the SI unit of radioactivity, defined as one disintegration per second.

Now, let's compare the activities of the three specimens:

1. Specimen A: 1 μCi = 3.7 x 10^4 Bq
2. Specimen B: 1 Rd = 10^6 Bq
3. Specimen C: 1 Bq

From the above, it is clear that Specimen B (1 Rd = 10^6 Bq) has the highest activity.

The activity of a radioactive substance is directly proportional to the number of radioactive atoms present. Therefore, the specimen with the highest activity will have the maximum mass.

So, Specimen B has the maximum mass.
