what is the correct answer ?? please explain ?

What is a humped yield curve? A yield curve where yields on mediumterm bonds are higher than yields on both short-term and long-term bonds. A yield curve where yields on long-term bonds are higher than yields on shortterm bonds, but not as high as yields on medium-term bonds. A yield curve where yields on shortterm bonds are higher than yields on both medium-term and long-term bonds. A yield curve that has a flat line with no slopes
