Escaped breadcrumbs

Hi all,
Can someone escape this line for me please?
I made other escapes but here i don’t know how, i read many about escape but this line is impossible for me:(

echo '<a href="' . esc_url( get_permalink( $post->post_parent ) ) . '" alt="' . esc_attr( $parent_title ) . '">' . $parent_title . '</a> ';

Thank you

echo '<a href="' . esc_url( get_permalink( $post->post_parent ) ) . '" alt="' . esc_attr( $parent_title ) . '">' . esc_html( $parent_title ) . '</a> ';

Hi

Just to get an idea you can check this code:

<a href="<?php echo esc_url( "https://codecanyon.net/" ); ?>" title="<?php esc_html_e('Codecanyon', 'YOUR-Text-Domain'); ?>"><?php esc_html_e('Codecanyon', 'YOUR-Text-Domain'); ?></a>
<input type="text" name="fname" value="<?php echo esc_attr( $fname ); ?>">

Thanks
