Answer 1

The correct statement is:

Iodine will indicate starch in a substance.

Iodine turns blue-black in the presence of starch.

The other statements are incorrect:

• Vinegar does not specifically indicate sugar; it is an acid, and while it may affect sugar solutions, it does not indicate their presence.
• Benedict's test is used to detect reducing sugars, not starch.

Therefore, the correct pairing is the first one.
