With some effort and customization, it possible to get close to what you want, however XmlSerializer will always place the CData nodes at the end of the container element. Your example XML shows the CData nodes between specific nodes of the container element. As long as you don't need this precise control, you can use How do you serialize a string as CDATA using XmlSerializer? to do nested serializations, like so:
public class Order
{
[JsonProperty]
public int OrderId { get; set; }
[JsonProperty]
public string Name { get; set; }
[JsonProperty]
public int Type { get; set; }
[JsonProperty]
public decimal Amount { get; set; }
[JsonProperty]
public DateTime Date { get; set; }
[DataMember]
[JsonProperty]
[XmlIgnore] // Do not serialize directly
[XmlWrapCData] // Instead include in CDATA nodes
public List<Option> ListB { get; set; }
[DataMember]
public List<string> ListC { get; set; }
[XmlIgnore] // Do not serialize directly
[XmlWrapCData] // Instead include in CDATA nodes
public Product Product { get; set; }
[XmlText] // NECESSARY TO EMIT CDATA NODES
[IgnoreDataMember]
[JsonIgnore]
public XmlNode[] CDataContent
{
get
{
return XmlWrapCDataHelper.GetCDataContent(this);
}
set

XmlWrapCDataHelper.SetCDataContent(this, value);

This will parse your provided XML successfully, and in return generate XML that looks like:
<Order>
<OrderId>2</OrderId>
<Name>Some Name</Name>
<Type>1</Type>
<Amount>100</Amount>
<Date>2015-12-07T05:10:49.6031106-05:00</Date>
<ListC>
<string>ListItem1</string>
<string>ListItem2</string>
</ListC><![CDATA[<ListB>
<Option>
<OptionValue>OptionValue1</OptionValue>
<OptionName>Option1</OptionName>
</Option>
<Option>
<OptionValue>OptionValue2</OptionValue>
<OptionName>Option2</OptionName>
</Option>
</ListB>]]><![CDATA[<Product>
<ProductId>1</ProductId>
<Name>ProductName</Name>
<Type>Product Type</Type>
</Product>]]></Order>
