The correct answer is option B. When you visit Florence, please visit Michelangelo's La Pieta. Option A is incorrect because Florence is the name of a city, and thus it should be capitalized. Option C is incorrect because the verb is missing in the independent clause. Option D is wrong as 'Michelangelos' is nor punctuated in a correct way as the apostrophe (') should be added before the s to indicate possession. Option E is not correct as the period is missing at the end of the sentence. Option B is correct because Florence is capitalized; it has a verb in the independent clause, the apostrophe that indicates possession is correctly used, and the sentence ends with a period.
