Explanation: 

Detailed explanation-1: -The root CA or trust anchor has the ability to sign and issue intermediate certificates.

Detailed explanation-2: -To verify a certificate, a browser will obtain a sequence of certificates, each one having signed the next certificate in the sequence, connecting the signing CA’s root to the server’s certificate. This sequence of certificates is called a certification path.

Detailed explanation-3: -An SSL certificate is a digital certificate that authenticates a website’s identity and enables an encrypted connection. SSL stands for Secure Sockets Layer, a security protocol that creates an encrypted link between a web server and a web browser.
