1. They are steroids, proteins, peptides or amino acid derivatives.
2. They are not produced by body organs and are mostly taken as supplements.
3. They do not influence the working of those organs which have secreted them
4. They act as co-enzymes and help enzymes to perform their function.

{'hormones': [1, 0, 2, 2], 'peptides': [1, 0, 1, 0], 'properties': [0, 0, 0, 1], 'enzymes': [3, 0, 6, 3], 'amino acid derivatives': [0, 0, 1, 0], 'steroids': [2, 0, 3, 0], 'proteins': [1, 1, 0, 0], 'supplements': [0, 0, 2, 0], 'body organs': [0, 0, 1, 0]}

Option 1 states that hormones can be steroids, proteins, peptides or amino acid derivatives. This is correct. Hormones can come in different forms, including steroids like testosterone and estrogen, as well as proteins, peptides, and amino acid derivatives like insulin.

Option 2 states that hormones are not produced by body organs and are mostly taken as supplements. This is incorrect. Hormones are produced by various glands and organs in the body, such as the pituitary gland, thyroid gland, and adrenal glands. While some hormone supplements are available, the majority of hormones are naturally produced by the body.

Option 3 states that hormones do not influence the working of those organs which have secreted them. This is incorrect. Hormones are chemical messengers that are released into the bloodstream and travel to target organs or tissues, where they influence various physiological processes. For example, insulin, which is produced by the pancreas, regulates blood sugar levels.

Option 4 states that hormones act as co-enzymes and help enzymes perform their function. This is incorrect. Hormones are not typically involved in enzymatic reactions as co-enzymes. Their primary role is signaling and regulation of various bodily functions.

Therefore, the correct answer is option 3, which states that hormones can be
