Explanation:

When lifting weights to strengthen arm muscles (which are skeletal muscles):

• Skeletal muscles have myofibrils (so the statement "They lack myofibrils" is false).
• Skeletal muscles are voluntary (not involuntary, so "They are involuntary muscles" is false).
• Skeletal muscles have a banded (striated) appearance (so "They lack a banded appearance" is false).
• Skeletal muscles have tendons that connect them to bones.

Answer:

They have tendons that are connected to bones.
