If z = x · y, then z will grow at the rate of (11ea895d_4d3b_f40c_8397_236fa915d90a_TB4305_11 + 11ea895d_4d3b_f40d_8397_5b53ece338dc_TB4305_11) = 22 percent. Therefore, choice A and C are incorrect.

If z = x/y, then z will grow at the rate of (11ea895d_4d3b_f40c_8397_236fa915d90a_TB4305_11 - 11ea895d_4d3b_f40d_8397_5b53ece338dc_TB4305_11) = 0 percent. Therefore, choice D and E are incorrect.

Thus, the correct answer is B, with z growing at 6 percent.
