问题 If 4 and 11 are the lengths of two sides of a triangular region, which of the following can be the length of the third side?Ⅰ.5 Ⅱ. 13 Ⅲ. 15

选项 A、Ⅰ only
B、Ⅱ only
C、Ⅰ and Ⅱ only
D、Ⅱ and Ⅲ only
E、Ⅰ, Ⅱ, and Ⅲ

答案 B

解析 A leg of a triangle cannot be greater than or equal to the sum of the other two legs. This principle eliminates both Ⅰ (11＞5+4) and Ⅲ (4+11=15). Therefore, Ⅱ is the only acceptable length.
