16. Which type of solder is used when soldering an automotive electrical connection? A. Rosin Core B. Zinc C. Silver D. Acid Core

## Step 1<br />The problem is asking us to identify the type of solder that is typically used when soldering an automotive electrical connection. The options provided are Rosin Core, Zinc, Silver, and Acid Core.<br /><br />## Step 2<br />Rosin Core solder is a type of solder that is commonly used in electronics and electrical work. It is known for its ability to provide a strong, durable bond and its resistance to corrosion.<br /><br />## Step 3<br />Zinc solder is not typically used in automotive electrical connections because it can be too brittle and may not provide the same level of durability as other types of solder.<br /><br />## Step 4<br />Silver solder is also not typically used in automotive electrical connections because it can be too expensive and may not provide the same level of durability as other types of solder.<br /><br />## Step 5<br />Acid Core solder is not typically used in automotive electrical connections because it can be too corrosive and may not provide the same level of durability as other types of solder.
