Are you referring to this question and choices?

 Some of the composers who contributed to the creation of the golden era of American musical theater were George Gershwin, Cole Porter, Richard Rodgers, and Frank Loesser.

A.  William S. Gilbert and Arthur Sullivan.

B. George Gershwin, Cole Porter, Richard Rodgers, and Frank Loesser.

C. Giacomo Puccini, Giuseppe Verdi, and Richard Wagner.

D. Stephen Sondheim and Andrew Lloyd Webber

If so, then the answer would be letter B. 

On the other hand, the statement "The golden era in American musical theater was created by Gilbert and Sullivan in the late nineteenth century." is not true. 

the sculpture i am pretty sure you are talking about is the statue b. the david statue now lives in the galleria dell'accademia, florence, italy. it was made by ‎michelangelo.
