How to complete laboratory courses after building fire?
As an experimentalist myself, I feel strongly that that hands-on part of laboratory is an important part of the course, but ...


The students have presumably already done some of the planned hands on work, so option #3 would not be a total loss on this front.
Analysis of data is not generally the same as classroom problems, and is also an important part of the laboratory experience.


Toward that end I would suggest 


Investigating option #2 vigorously in hopes of recreating or substituting for some part of the hands-on work that would otherwise be lost. Try to get all the students one more hands-on experience if at all possible.
Use option #3 to address the analysis skill you were hoping to teach. Give them not only the data, but the equipment, methods and technique parts of lab reports from previous students (be sure to get permission where this might be needed).
Use a library assignment to get them thinking about the skills they are not practicing. Perhaps assign them each to report (either a oral presentation or a paper) on the methods used to perform [some common analysis in your field] when that technique was new and the equipment was not as forgiving as today. 


And declare it the best you can do under the circumstances.
