Hi @UdhayachanderG7215,

While understanding this example you have to keep in mind that pattern inheritance is automatic or implicit while direct inheritance is explicit. Hence while B can inherit from C as the inheritance type here is explicit. Same can not be done via A as C doesn't comes in its inheritance hierarchy.

For sake of understanding lets consider classes as below 

• A - Loan Class
• B - Finance Class
• C - Banking Class

 Now lets consider the example you have given

Class A inherits class B via pattern inheritance

- Means class name(pattern) would something be like "MyOrg-Finance-Loan" 

Class B inherits class C via directed inheritance,

- Means "MyOrg-Finance" can inherit explicitly from "MyOrg-Banking"

would class A inherit class C?

- There is no explicit inheritance define for Loan hence it cannot inherit from Banking class as it doesn't falls under Loan's pattern inheritance path.

Thanks, Ankit
